Ford Ranger / B-Series :: 1994 - Running Hot - Loss Of Power
May 29, 2017
So I got everything fixed on my 94 ranger so I thought. Now it runs right on the "L" on the idiot gauge on 90 degree plus days running the AC. Also it seems to lose power at times and not even want to do 70. I think new coils, new plugs and wires may work. I also have an intermittent check engine light that pops up on occasion, but clears when you kill the motor and start it back up. I was really starting to like this truck despite it not being my style(I like square body rangers) and it being a 4 cylinder. I like the MPG but am starting to think the 200k engine may be fading

1994 Ranger .. Last wednesday I had to get a jump because the lights where left on. Everything was normal on thursday. Friday morning. I went to go start the truck and notice that it would try once to start and then try a second time and it would start. Today I was driving it. The check engine light came on and when I get the RPMs up to shift up, I would loose all power and have to wait till it gets down below 10mph before I would get the power back.

I am working on my buddy's 1994 Ranger with a 2.3L I4 that has been going thru a large amount of engine coolant. The trucks has approximately 180,000 miles on it. When I had it parked on concrete I have not seen any signs of coolant on the concrete or any signs of coolant leaking. The next place I checked was inside the cab to see if there was any coolant from the heater core and there was not. The water pump has been replaced a couple of years back. I replaced the spark plugs today and did not see anything on the plugs that I would have thought were signs of coolant in the combustion chambers.
With that being said I have not worked on a vehicle with a leaking head gasket before. Would there be any visible signs on the sparks plugs? If so what would I be looking for? When standing in front of the vehicle with the engine running there is a slight smell of antifreeze being "vaporized". Are there any noted issues with this engine that would cause this? Are there any other things I should check? Could it be a leaking head gasket causing this? If so how can I check for that?

Got a problem with the '94 Ranger. Something keeps draining the battery. For reference, the truck is an XL, manual 4x4, 4.0L, 5-speed. I've been trying to keep driving it so I could try and diagnose the issue. At first, as long as I cranked it every day, it stayed charged up, but now it has gotten worse. It will run down in an hour or two. I know figuring this kind of problem out is tough, but I thought maybe some others of you may have experience in this area that might benefit me.
Based on a gut feeling, my first idea was that there was something going on inside the AC compressor. So, I disconnected the compressor, but that wasn't it. My plan at the moment is to replace the wiring harness between the battery and the starter. The current harness is pieced together (not my doing), and whether it fixes this problem or not, it needs to be done. Another thing I've thought about is the ignition switch. It acts "funny" to me, but it has never really given any trouble.
My son needs to take this vehicle back to college with him in a couple weeks, and I need to get it figured out.

Engine runs rough at idle. Two plugs are black and just replaced head gaskets. I installed new short block and new heads six months ago. I can't seem to figure out the problem and I would like to trouble shoot more before tearing heads off and going any further.

1994 reg cab 4.ol 13ok.. my wife just got it, been doing some small things like replaced dome light, replaced cargo/third brake light, truck starts and seems to run ok. but i get a headache in it which i believe is carbon monoxide, has a leak or something? i text previous owner, he said he replaced 02 sensors, but didnt say if they were bosch or a good brand.. also trucks has a oil pressure and coolant temp gauge fitted on by the gear shift as the dash gauges for those functions are out. Does this mean the CTS may not be working and affecting fuel/air I do not know these trucks i only just found out what this strange silver looking thing was it is the IAC, I Believe, then there is this black plastic vacuum type cylinder by the passenger side firewall, what is that? and right against the drivers side fire wall is a small reservoir type thingy, is this something to do with ABS? i do have an ABS light on, was hoping it was the bulb out on the third brake light or something quirky like that no such luck its still on after starting engine. but i am concerned about this running rich/strong smell as we really cant take it far as is it, its dangerous, may have to get a smoke test? Just got the truck, trying to get caught up..

Background - I just got done changing a few things... Exhaust Manifold/gasket, battery cables, valve cover gasket, oil cooler gasket and hoses, power steering pump and hoses, and ball joints. Most of this has nothing to do with the issue that came up as I am driving it back to return it to her.
While out on the freeway, I initially notice subtle power losses and surges. These quickly escalate into almost total power loss with back firing, sputtering and much more noticeable surges in power. The check engine light was turning off then on a few times before pretty much deciding to stay on.
So I nurse it back home on back roads due to its inability to maintain freeway speeds. I proceed to check everything I touched paying special attention to the exhaust manifold and surrounding area. The new manifold came from the j/y and was barely used so I had initially just stuck with the O2 sensor that came with it; I changed this to the one the vehicle had previously been employing as it was not exhibiting these symptoms until after the job was done. I also double checked all the hoses, intake tube, wires and connectors; everything is connected.
From here, I research the method of pulling codes on OBD-1 vehicles by making the check engine light flash. It flashed a 111 and a 172 at the same time; the information I could find said the 111 means everything is normal, and the 172 suggested O2 or MAF. I am reasonably sure the O2 is not the problem so I focused on the MAF. Disconnecting it while running seemed to improve the way it idled so via the process of deduction, which also included the consideration of typical symptoms of MAF sensor failure, I proceeded to replacing the MAF sensor which amounted to little improvement.
At this moment in time the check engine light has not returned but it is clearly not in a drive-able state of being. It actually seems to have ever so slightly improved though.
Additionally, the symptoms only exist when the engine is hot and has been driven; it drives normally for 5-10 minutes until it gets to operating temperature then it starts to crap out. After changing the MAF sensor, I let it idle for 20 minutes and it was fine until about 2 minutes into the test drive.
Speculation - I am thinking spark plugs could also be a culprit as its has been forever since a tune-up but the sudden onset of this condition make me doubt this a little; it also has 8 plugs so even if one or two crapped out it should still run better than this I would think.

This has happened before on my 98 ranger 2.5. You can drive it 10,000 miles without any issue and then all of a sudden you take off and there's no power but it quickly returns. Within the last year I've changed fuel pump assembly, fuel filter, injectors, cool packs, and plugs. Is it mass air flow? It seemed to happen a lot more after I cleaned it. My scan tool is amateur but it has a maf reading in lbs. What should it be while driving? Fuel pressure is always between 65-72 when I check it within specs according to my book.

So, a couple of months ago, my Ranger lost a lot of power going down the road, and when I came to a stop it died, and wouldn't start. So I got it started by roll starting it, made it to a friend's, and then back home. I've put new spark plugs and wires in, and it needed it, badly, but it didn't work. I got a couple of codes off of it,
P0302- Cylinder 2 misfire detected(which I fixed with the spark plugs)
P1443 - which I can't find a definitive answer for
P0500- vehicle speed sensor malfunction
P0171- system to lean (bank 1)
So, the truck will turn over, and if I give it a lot of gas it'll start at stay started for a few minutes, but then cut off. When it is running it's running very very very roughly.

Bought my third 88 ranger today, drove it 55 of 60 miles home and it died. It lost power and acted like the coil was going bad. This one is a 2.9 5 speed 4x4. The a/c compressor is gone; but the 365 a/c works okay, or did.
My daughter was following me in her car; by the time we got back with my F150 and a chain, it started and ran until it was a half maile from home then lost power and died again.
Drug it home, put a new coil on and it started and revved up fine. Went to move it a couple of hours later and it will crank with the starter, but not fire.
I am getting 12 volts to the primary side of the coil, is there any way to check the TFI module without taking it off the distributor? (they are so accessable).
Or is there something else that I need to check? I really don't want to just throw money at it, I like to know for sure what is wrong before I buy parts.

Background- 2000 Ranger, 3.0L 2WD 170,000mi. This truck is not my daily driver, i try to drive it once a week.
I've never had this issue before... I drove all over town yesterday; multiple stops, no issue. Today i go to do the same thing and upon accelerating out of the driveway i lose all power for about 3 seconds. I get power back for about 3 seconds then lose it again. This continues for as longs as i'm driving. Also, no CEL. I go back to the house to look things over, can't find anything staring me in the face really.
Truck idles fine and the issue is not present when i run up the RPMs in park. I've been reading some other threads about similar issues and most replies begin with checking the regular maintenance stuff i.e. TB, MAF, IACV, pcv, etc. It seems like a complete loss of fuel or spark...but only when in gear with constant throttle???

My ranger sounds like it's revving up real high when I take off but don't have much power. Know what this could be?

I have a 94 Ford Ranger 4x4 4.0 V6. It has developed a rough idle and has lost i fair amount of power. I cleaned the maf sensor and iac valve. Along with replacing an o2 sensor that was reading bad, with no improvement. The guys at O'reilly took a look and think I may be dealing with a timing issue or a warped valve. My question here is to found the culprit? I'm very inexperienced at working on vehicles and am damn intimidated by the scale of a project like timing. I should add that while traveling on the highway in high gear at low rpms, it develops a rough stutter. I can either power through it or ease off to get it to stop, but it resumes shortly after. It almost acts like an egr valve stuck open when on the highway. But that doesn't account for the rough (a consistent put, put, put...) idle.

2002 ranger edge 3.0 5spd. Truck idles perfect, but when you get rolling and higer rpms feels like the engine is missing. loos of power and shakes. I replaced the usual, plugs and wire's, seemed to work for a bit but came back. I cannot get any info on the scanner and have checked all the fuses. I am thinking coil pack but don't understand why it idles perfect and only misses under acceleration. No check engine light on.

My brother's 87 ford ranger 2.3L truck began to have problems. It would be running great, then start to misfire, run rough, sputter, shake and loose accelleration then die. Then it wouldn't start back up for a long time, sometimes til the next day. Little by little, the truck would drive a shorter and shorter distance between breakdowns. He first tried some minor work himself, (basic tune up) - replaced his rotor, cap, plugs, air filter, fuel filter, but that didn't fix it. He went to one garage (big mistake), who said the fuel pump pressure was fine but said he found a broken wire on the harness grounding out and it needed new ignition module and replaced it. (Cost was $350.00+), Garage promised to honor any additional work nec if it continued to have the same problem, and would be free of charge.
Five more breakdowns later and two more "better quality ignition modules", new battery terminals, and 1 new computer later, this joker did more unauthorized work and demanded another $200+ besides the fact of breaking his orig agreement "free of charge" if any further problems! Needless to say, second garage fixed the truck by replacing the magnetic pickup, part # DU 30-C (an electrical part that goes in the distributor and pulsates a current to operate the timing) (it does something like that) and the truck has been driven approximately 40-60 miles as of today, (3 days later), without breaking down. All the other times when picked up from incompetent garage, it wouldn't go more than 1 - 7 miles before breaking down and each time they didn't fix it.

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..

2000 Ranger 2wd 3.0 ... I bought my truck last summer for $1k from my neighbor, it has hit a deer so the grill is busted,front drivers fender bent up and bumper is bent all to heck. The old girl is rock solid reliable though and gets decent mileage with cruise heat and ac so I'm happy.
Anyways on to the point, I am having two big issues with it, the check engine light randomly comes on and causes it lose power sometimes at others you don't notice it. I have not been able to get codes read because it goes off every single time I go to someplace with a scanner. The light will usually go off if you floor it for a long stretch maf maybe?
The other issue is the transmission, I don't know for sure which tranny it is but the overdrive button does not work at all even though the fuses are good and when I drive down the highway second gear you have to let off for it to shift sometimes ( I've been leaning towards the valve body gasket for that) and lately it has started a horrible vibration kicking out of overdrive or just downshifting on hills etc.?
I forgot to mention it has 255k miles on it and I don't know the history besides the balljoint I replaced this week and radiator when I bought it.

Ok I've been plagued with this very random misfire/power loss/hesitation problem going on a couple of months. You could drive the truck anywhere from 50-300 miles without having an encounter of this problem. It seems to do it now mostly on contiguous long trips over like 30 miles. It one time threw up a P1131 code which quickly went away on it's own. This is a list of stuff that has been recently changed: plugs, wires, coil packs, air filter, pcv valve, fuel injectors, tps, idle air valve, MAF cleaned, fuel filter, and egr valve.
I sprayed with brake cleaner for vacuum leaks around the intake tonight after driving a continuous 50 mile round trip it messed a few times on the way back. When I sprayed the EGR valve mounting area it idled rough when it was hit with brake clean and idled up. So there's a leak there. Or is it stuck? It will be driving normal and usually when you come to a stop the engine will start missing really bad and then when you take off there's no power at all. You keep your foot on the gas and eventually it will feel like all the power is just turned on.
If it does it while you're driving highway speeds it will feel like you've lost a cylinder but it's not as dramatic as when you come to a stop and it starts missing. I can't be 100% but I don't think the EGR wasn't leaking before I replaced it and it was still doing the same thing. I'm wondering why the Check Engine Light won't pick up an obvious misfire when you can you actually feel it. And why if it was the vacuum leak would it only start doing it after many miles of driving?

I have a 2002 Ranger with a 3.0/auto with about 180K on it. It runs good but for the past 6 months I have had a problem starting it. It does the same thing hot or cold but is a LITTLE easier when cold. It is very hard to start, you have to grind the started for about 30 seconds then it starts right up.
I checked to see if I could hear the fuel pump when the power is turned on and yes I can. But after checking the fuel pressure, there is no fuel pressure with the power on and the engine not running. Once the engine starts, there is about 65-68 pounds of fuel pressure - and the truck runs just fine. Starting is the only problem.
I was told I had to replace the fuel pump. Is the electric pump in the tank the ONLY fuel pump on the truck, or does it have a combination of the electric/tank pump and a mechanical pump on the engine?

My 94 ranger, 3.0 v6 began to sputter and jerk about a month ago. It does this when ever give more then lite throttle up until about 3000 rpm. I have replaced plugs, wires, coil and cleaned the air flow sensor. I feel like this has worked a little but the problem is still definitely present. When I hit 3k rpm if feels lie the truck begins to run correctly and almost like it had a power ban much like a dirtbike, but again it's just the truck running correct.. And above 3k rpm it runs great... and every so often the problem will completely disappear for 5 minutes or so, then come right back.
