OK,it's a Taurus but it's the 3.0 Vulcan.On the highway crusing easy,now and then I'll get a stumble.It's like the key is turned off and back on.The tach stays steady but the car stumbles like the key was cycled quickly.I had to put a fuel pump in it a few weeks ago and now it is starting every time but this stumble has me stumped.
View 5 RepliesIm getting an intermittent stumble with a check engine light. I have a 1990 Ranger XLT with a 2.3L 5spd. I pulled the codes 32 41 88. I looked them up but Im not sure what to check next. I have done much searching on several sites but havent found much. OBD-1 eludes me.

What does it all mean??? What would you check next?
My MILaw Truck 1992 ranger isnt running good and I need to get it going
Only a P0111 at this time IIRC
We started the truck tonight and idel ok Could see the motor Stumble every so often. She went to drive it and it Cuts out under Load Or you must rev it up to keep it from Stalling.
And if it does Cut out you have to let it sit for 5 minutes to restart what is Weird is it dont Smell Flooded either I smelled the VAC Line to the FPR and it was DRY and Did NOT Smell like Fuel.
It was dark didnt do much trouble shoot as the Flashlight died. I wonder about Fuel Filters. And Also about the Idel Control. The Mis or Stumble seams Random
Any testing I can do I have a DVM and that Code Reader. Might have to find something to check fuel press with where would I check it at the fuel rail I assume. Going to try and go over the Basics tomorrow If there is Anything Specific I should check?
1996 Ranger 2.3. I bought it from a friend 2 months ago. 228,866 miles. The motor seems to stumble as I'm going through the gears. I've cleaned the mass air flow sensor and installed new air filter. Check engine light has always been on, O'Reillys hooked up their computer to it and said Emission Valve Malfunction. I see the charcoal canister, then I have 2 electrical sensors on same line. First one from canister looks like what Rockauto.com shows as a Vapor Canister Purge Valve. The photo has it with a yellow orangeish top. I don't know what this 2nd sensor is. It has a blue top.
View 2 Replies1988 4.0 - noticed fuel mileage going down and an occasional stumble for a while but now I am getting some black smoke more when I let off the throttle than when I going down the road if I rev the truck get all kind of black soot all over the floor otherwise runs fine idles fine the iac has been replaced air filter replaced check the fuel pressure regulator for any gas leaking into the vacuum line and its clean.
View 14 Replies1987 Ranger and the computer will not communicate. I'm trying to check for codes because of a rough idle and stumble when starting out from a stop. Check engine works but won't flash when using a jumper across the data link. Used a OTC scanner but it only times out and comes up "no data". Where to go from here?
View 7 RepliesI have a 1994 4x2 shortbed standard cab Ranger XLT. It has the 4.0 OHV engine, A4LD Automatic transmission, and 195,000 miles. Under average driving conditions, it operates fine. It shifts up through the gears much like it always has, although the shifts may not be quite as firm as they used to be.
If I'm at cruising speed and step harder on the accelerator, it downshifts, RPMs increase, and it upshifts rather poorly, & then I feel a thump, (maybe the torque converter locking up when it shouldn't be?), and I'm in the higher gear. This seems to happen when it upshifts from 3rd to 4th gears for sure, maybe from 2nd to 3rd, but I'm not sure.
Again, it only seems to happen when I attempt to speed up from cruising speed, not from a stand-still. The transmission fluid and filter have been changed at regular intervals, and the truck has never been abused. The fluid is red in color, doesn't smell burnt, and the level is correct. I don't want to get rid of this truck if I can avoid it. It has been super-reliable and mostly trouble-free for the 16 years I've owned it. What might be wrong with it?
My '90 Ranger is experiencing a pretty bad misfire after doing a tune-up. I changed the plugs (gapped to .045), wires, distibutor cap, rotor button, air filter, fuel filter, and cleaned the IAC. It had a barely noticeable miss before the tune up, that's why I did it. Now, it's pretty horrible.
At idle, it's definitely noticeable, and at cruising speeds (RPM's below 3K) it bucks and surges. The weird part about it is WOT runs are as smooth and (somewhat) powerful as ever! At idle in neutral it will revv up just fine without any hesitation as well.
First thing I did was check the firing order, again and again. Made sure all my wires were properly seated on the plugs and on the distributor prongs. Pulled the plugs back out, they were all clean and properly gapped. I pulled the wires off one by one to try to isolate the misfire, but every plug wire I removed made around the same impact on the motor.
Next I ran codes. KOEO, I got code 95 - fuel pump secondary circuit failure. Don't know what to do about this. Fuel pumps comes on at the turn of the key, relay clicks... KOER, I got 11 (pass code), so nothing there.
Then I hooked a fuel pressure gauge to the schrader valve on the fuel rail, and at idle pressure was a steady 35 PSI. I also removed the vac. line to the FPR while running to see if gas came out. I checked for vac. leaks as well.
Now not sure what to check now. I've checked everything I know to check, but nothing works....
Bought the truck 1000 miles from home, ran great, checked oil it was black and well used, coolant was milky and degas bottle had some pressure in it.
Drove 200 miles fine, 75mph lots of power, no smoke, no overheating.
While cruising felt slight stumble, and lost hot air from the heater (started blowing cold), saw temp needle move slightly (still under 1/2 mark) and pulled over. Truck stalled on the offramp, and I was not able to get it to fire. I checked oil and it was same dark black. Coolant was low, down to about 2.5 gallons.
Towed it home, oil change, coolant flush, new thermostat, rebuilt IPR, and it fired right up. Ran great, smooth. Noticed slight haze out of the exhaust at idle, and puffs of white smoke when on throttle. Checked oil and it was milky. Where to look?
Cruising down the highway, my 2001 Santa Fe engine suddenly cut out. Would crank, but not fire. Not hearing a sound from the back when I flipped on the key, suspected the fuel pump, which I replaced. No go.
I'd pressed the fuel pump reset switch under the hood - checked it again. Should the switch, when it's pressed, stay in a locked position, like when you do a reset on a GFCI electrical outlet? Or is it normal for it to have the up/down 'play' in it?
Also noticed a strange buzzing on the other side of the engine compartment -- was the unit (don't know what it's called) that the throttle cable feeds into - hooks onto a pulley. The buzzing was intermittent and inconsistent, but it was happening with just the power switch on.
Oh, and did replace the fuel pump fuse, too. While it's at 280.000 miles, not quite ready to give up on 'er yet!
I got a 1997 Ford Ranger 2.5L that randomly jerks on the highway and I can't figure out what the problem is. This morning I had a 3 hour drive and it was fine on the first hour and then the last 2 hours it will randomly jerk on the highway and then be find for a little bit and then do it again. I don't know what the issue is? I did scan my car this morning and did have two code P0141 and P0113 not sure if these would have anything to do with it or not. Also my speedometer is hit or miss when it works, other than that everything else is fine on the car no check engine light or anything like that.
View 6 RepliesAbout a month and a half ago I was doing 70mph down the highway and the truck began to lean out sputtering and sounding like fuel was not getting there, when I pulled over on the side of the highway because it killed itself and then the car would not start I noticed the ox sensor for the 3rd cat was ripped out from being caught on the driveline, I removed ox sensor and car still wouldn't start. I took the truck to my buddies shop and after a new ox sensor was installed with some effort the truck started 30minutes later, I did not think this was reason for the truck to not start but after a day it was running like a top again, little did I know. Last week driving down the highway ironically in the same spot as before the truck did the same thing sputtered to a stop and would not restart.
Side Note: on both of these occasions after the truck would sit for a day it would start run for about 5 seconds and die???? So I had it towed home again and began reading FTE, I saw posts about fuel pressure and spark and P0176 code for Flex Fuel, Inertia Switch and so on.
So I started with Fuses they all look good then the most popular post and 2 of the codes were P0176 and P0177 for flex Fuel they read OBD II flex fuel wont start....Another code was for EVAP and 3 codes for heater bank(it turned out to be a fuse but is or could something trip this to send the car down this path?
I Then figured I would try the Fuel Filter..This did not work.
2nd I tried was Fuel pump pressure is good based off others posts.
So I bought the Flex Fuel Replicator that eliminates the need for the flex fuel sensor, from the guy in Portland, well this didn't work either. Next I went to spark checked all plugs they smelled like gas and were slightly fouled I had just replaced these about a year ago but hell why not? so I replaced and got nothing still also checked the oil had some gas smell to it but my buddy said this was normal with trying to get it to turn over without success.
Checked inertia cut off it was normal, checked fuses they were good(except heater which has been replaced). Now I am stuck...

This 2003 ranger 3.0 v6, run very hard at idle, yet it runs and you can drive it around town, ""at"" low rpm, and no hills but it gets from point a to point b
I have no pre ingintion, but a plug that was only 60 days only was burnt out completely on 3rd cyl. bank 1 or as ford call it #3, i am telling you this thing seem like it running on 4 cyl,s kicking back and forth, and replacing everything above made no difference.
On the highway, as long as it is flat or down hill 75-80 mph, as soon as a hill or power to pass is needed it bogs down and slows it self to about 45 mph, I have been though everything i can think of and my next move to to start pulling heads, but i wanted to ask here first.
A while ago I had a '99 Ranger. Long bed, regular cab, 2wd, 5-speed, 2.3. I had really poor acceleration. I was used to Toyota pickups with the 2.4 22RE, and the Ranger was considerably slower to come to highway speeds.
So, I took it to two different dealers, and they told me "that's just the way they are." I guess I believed them and sold the truck. Now, I am kind of thinking about another Ranger. Do people here think the '99 2.3 has an acceleration problem? Are there certain years to avoid the I4 in a Ranger?
I've got a 2003 Ranger 2.3L DOHC, 5 speed, 2WD. It has a check engine light with codes :
P0316-Engine Misfire Detected On Startup
P0704-Clutch Switch Input Circuit Fault
P2195-O2 Sensor Excess Lean Signal Bank 1-Sensor 1
P0171-System Too Lean (Bank 1)
The truck runs fine when coasting or accelerating but when holding a steady light throttle to maintain speed the truck starts bucking and jerking. It's doesn't feel like a misfire, more like a fuel cut out condition. When this happens and you come to a stop, you can smell that the exhaust is very rich coming out of the tailpipe. I've already replaced the upstream O2 sensor and I did a tune up about 15k ago. I'm thinking fuel pump or fuel pressure regulator. I doubt if this is related, but on start up (more so on a cold start up) the A/C compressor clutch kicks in and out 3-5 times and makes a terrible racket.
I recently picked up a 93 ranger sport 4x4 with 2.3L engine and 5spd.. Has run fine for the first 2 weeks of ownership but yesterday morning, it started cutting out on the highway. When I say cutting it is like all loss of power for a brief instant and then it right back without even losing any speed, I could watch tach drop from 2500 to 2k and then right back to 2500 again..
Did it sporadically all the way home about 10 miles sometimes once in a mile other times 6-7 times in a mile. Truck has 126k on it, and within last 26k miles PO replaced timing belt, coil packs, plugs, wires, ICM, and just before i picked it up from him a new EGR and fuel filter.
No check engine light
Fast forward to this AM
Wouldn't start at all, i can hear fuel pump spinning and she cranks and cranks but no start up.... played with multiple things including the ICM but found 2 of 3 heads rounded off so i cant remove it until i can get it in to my garage and dremel those suckers off..
Went and bought a replacement ICM figured i could plug it in run a ground from the bottom left hand bolt hole so i could get it fired up and in to my garage.. plugged the new one in grounded it and it still wouldn't start...
So I decided to replug the original ICM back in and grab my spark plug tester, remove number 3 plug wire on passengers side insert the tester and have my wife crank it over and wonder of wonder it fires up...
shut it down remove the tester and have her start it up again and it fires right back up so i let it warm up for 15 minutes.. grab my autoxray.. shut it down hook up the scan tool and run the KOEO scan.. gives me a passed 111 code... OK lets start it back up and run the KOER test.. wont start back up.. reinstall the spark plug tester to #3 wire and NOW it has no spark..
I have a 97 Ford Ranger / 2.3L / 4 cylinder (L4) / 5 speed manual / XL Supercab / 140k miles. I had been having some Check Engine issues and ran rough in town stop light to stop light. But was fine on the highway.
On several visits to the parts store, their OBD tester showed:
PO303 (Cyl 3 misfire detected)
PO141 Bank 1 Sensor 2 O2 Sensor (heater circuit malfunction)
PO171 Bank 1 Combustion Too Lean (the most recent new code to show up)
And the following would show up sometimes, but other times not:
PO 402 EGR Flow - Excessive Detected
P1409 EVR (I cant remember the exact error message for this)
Regards the PO141 code, O'Reilly's sold me a Bosch O2 Sensor (Bosch 15719) and the sales rep told me it was the sensor closer to the engine. And with the attached cable length on the sensor showed was indeed the sensor closest to the engine. But I've been advised the Sensor 2 is for the 'downstream' sensor, furthest away from the engine. And the other sensor, that I replaced is the upstream sensor. And the error continued.
Then back issues showed up and I had back surgery this past year and thus drove the vehicle sparingly. Never resolving the check engine issues. (My bad). Ran on the highway ran fairly well. But recently noticed longer acceleration times and unable to top 65 in 5th gear. I bought spark plugs and plug wires and had plans to change next week.
Yesterday as driving down the Interstate, was 90 miles into my trip, I noticed loss of power even in fourth gear. (note it was the hottest day of the year at 100F). It seemed I used more gas than usual for that distance. I stopped for gas on the Interstate and power seemed to improve. Then about 130 miles into my trip I hit some heavy stop and go traffic, and wasn't able to keep an idle and the engine died numerous times if/when I didn't give it gas at a dead stop. The heavy stop and go heavy traffic and the issues persisted for a half hour for more than five miles. Then when traffic opened up the truck seemed to have a bit more power in 4th gear again. And up to that time all my dash gauges were showing fine. Then a couple miles or so down the interstate, driving 65mph in the inside lane, the check engine light started flashing quickly. And at the same time a sudden loss of power, rough sounding engine with heavy white smoke coming under the hood. And looked back in rear view mirror, with nothing but heavy white smoke. Managed to cross three lanes in heavy traffic and was able the vehicle to the outside emergency lane, finally coming to a stop.
Looked under the hood and saw oil dripping everywhere but with all the oil everywhere I could not find a prime source. Looked like the oil came from the top end of the engine and dripped down. Measured the oil at the dipstick and it seemed like I was at least a quart plus down (I checked the oil before I left on the trip). And it didn't look like any water was in the oil. And my radiator overflow tank was at the proper level. So I figured I lost all that oil during that period of "white smoke".
So had my vehicle towed home. Today in daylight, I did some more inspection and removed the air intake system (hoses and canister) from the air filter to the throttle body. There was significant oil up to the canister piece that fits on the air filter canister (but no oil in the actual air filter), and significant oil inside all the hoses up to inside the throttle body (up to the butterfly which I could see),
When I disconnected these hoses I noticed the blow-by hose connected to the intake hose system was not connected to anything. And a tube opening on the valve cover was open without the a blow-by hose attached and, with no clamp. So I assume all that oil and came out of that blow-by tube on the valve cover, (white smoke created by hot oil hitting the engine).
So appears to me that its not a blown head gasket or worse, which I first feared.
I have the vehicle parked at home.
QUESTIONS: So what are the suggested steps to troubleshoot and repair? Besides reattaching everything and putting a clamp on the blow by hose? And installing new spark plugs and plug wires. I previously replaced plug wires around 60k, even though the manual recommended 100k mile replacement. (And a couple yeas back I had the dealer replace the PCV, which was recommended in the manual and included in the warranty. The timing of the initial check engine lights appeared shortly thereafter).
Is there suppose to be a large amount of oil in the air intake system after an incident like this and should I try to clean/flush out the hoses and the inline canister?
When I disconnected the inline canister from the hoses in the air intake system, unfortunately I failed to document the direction which the canister goes. It has outside markings "ADP with a forward arrow with some horizontal lines, and then at the other end upside down markings with a greater sign PP less than sign. Should the forward arrow point toward the throttle body or toward the air filter (I'm thinking in the direction of air flow, toward the throttle body). I've taken some photos of the engine with air intake hose system unattached, if that might work...
On my '91 last week I was driving on the highway about 60-65 when all of a sudden the speedo dial started climbing to 70-75-80-85 and past. The odometer seems to be working ok? Still when I drive it still operates in the same manner. It never bounces around or falls back. The needle is sort of stable such if I maintain a speed the speedo will maintain even though it's incorrect. There is a slight wavering of the needle meaning it's not as stable as it use to be. With the odometer working I was wondering and don't know. Does the cable drive the needle or is it electrically controlled? I'm thinking of grabbing another instrument cluster it that is the problem, I'd like to know more about it and understand how it works so I don't just throw parts at it until it's fixed.
View 1 RepliesThe other day I pulled into the parking lot put it in park and let it idle for a couple minutes, it stumbled and when I started driving off it was missing. I pulled the valve covers off and check the connection.. I drove it home and it had a bad misfire at 1500 RPMs. The truck shook violently at that RPM but when I got it up over 2000 smooths out..
View 1 RepliesI got a funny shifting issues that happens infrequently that I can no figure out. It happens after driving the car for a while on the highway, but not every time, and not just on the highway.
Here is my problem... when cruising down the highway the check engine light will come on stay on for a around a minute, the the check engine light will turn off, then of which my truck will lose power, not accelerate no matter how much I stomp on the gas, until my speed drops to under 55mph.
Once I get down to 55mph the truck will drop 2 gears into 3rd gear and then I can accelerate back up to speed. This will repeat every few miles. The computer will not store the check engine code, so no codes are pulled.
As the title says the beast died on me yesterday morning going into work.
Situation : 5 F @ 7 Am
1/4 tank of fuel that has been treated
cruising at 70 MPH on the highway using the cruise
Going into work the other day the truck died on me as i cruised along at 70 MPH on cruise, I go to get out of the way of a car. As, I step on the accelerator X falls on its face. I look at the dash and there are no idiot lights on, gauges all look good. I navigate to the shoulder 3 lanes over and park it. As soon as it is in park it dies and will not restart.
I call AAA and sit there waiting for the truck to show up. After about 10 mins I try to start it again it stumbles and dies. 2nd try it fires up and is running rough. I make it to the nearest gas station and fill up. Then I go to the parts store and pick up the 911 fuel treatment and put it in the tank. I also use a scan tool on it and no codes. Truck ran fine after all this.
I go to start it after work, it starts and dies. I start it again and it sounds like it is running on 2 cylinders and there is a large puff of smoke out the exhaust which goes away after it is started.
After it warms up it runs and drives fine, no issues! So I looked at my extension cord I plug it into and realize that the timer was bad. New timer and verify it works. Go to start it today and it starts right up and idles and runs fine. Is it possible that the fuel gelled up due to the timer being bad and the block heater not turning on? Or am I missing something?
