When I'm driving it starts to cutout (but it never dies) and it won't stop cutting out until I floor it and then it's fine for a little bit and it starts doing it again.
View 1 RepliesI have a 1987 Ranger 2wd, 2.9, 5sp that feels like it is cutting out when accelerating. The only code in the computer (KOEO) is 67, which according to the manual is neutral drive switch (NDS) circuit open. What to look for? Can the neutral drive switch be the problem?

View 14 RepliesMy 88 2.9 ranger keeps heating up badly while idling. Was waiting in the drive-thru at Wendy's and it was taking them longer than usual, the temp guage started climbing closer and closer to 'H'.. I revved it up a bit to a fast idle (1500-2000rpm) and it did not work much... figured the gauge was being screwy. But when i finally got my food and started moving the truck was pinging..it really was hot..
But as soon as I got her moving at a steady 40mph, engine cooled back down to normal temp as if nothing ever happened..i put an extra wide two row aluminum radiator from a 4.0 explorer in it, fan clutch is not very old, no coolant leaks that i can see.. can't figure out why it heats up so much so fast at idle. Not enough air or coolant flow?
Any way to tell if the ECU is faulty? I hooked my analyzer up to my friends 1988 Ford ranger 2.3L and it wouldn't even detect that the ignition switch was on. He was driving it the other day and is shut off on him while he was making a turn and it wouldn't start back up. We have rebuilt the distributor by replacing the pick-up, rotor button and cap, and we had the ignition module tested and found it was good. We have also replaced the coil. When the ignition is turned to the on position, the fuel pump comes on and never cycles off.
View 8 Replies88 ranger. 2.9L manual. Just bought this truck. It ran great when I bought it. After a day or 2 it would idle rough. Almost die but it wouldn't. No check engine light. It seemed to do this intermittently. Some times I'd start it and it be fine. Other times I'd start it and I'd expect it to die at each stop light.
Now for the last couple days it dies on every start up. It won't idle. It'll start right away and then die. I can keep it going by keeping the engine rev'd but the check engine light is one. If I keep it running and start driving down the road it'll drive with the check engine light on for about 5 minutes. Then the light goes out and it runs like normal, even at idle, until I shut it off. Then it's the same story at next start whether it's right after I shut it off or hours later.
It doesn't seem to matter whether the engine is hot or cold. When the check engine light is out, it runs great the rest of the time whether at speed or at idle. To me it sounds like a sensor is on it way out. I figure if it was vacuum, it happen at every idle, and if it was fuel it happen all the time or at least every idle. Tried to get a code at parts store but the reader wouldn't work. It couldn't tell it was plugged in the the truck for some reason.
I have tried about everything i know about cars on this truck!! It ran great when I got it until a head gasket got blown so I tore into it and replaced them both torqued heads to specs. Made sure valves wasn't to tight. Distributor is in correct spot timing is correct had ignition module tested good!!! Coil tested good replaced both fuel pumps and put new tank and sending unit in the truck b/c it needed it new fuel filter replaced return line firing order is correct 1 4 2 5 3 6 it is getting fire it will crank and crank sometimes act like it is going to start then not also I can get it to run for about 3 sec on 3 or 2 cylinders it seems to have plenty of compression as well!! only thing really I can think of that could be wrong is computer? Also one last detail tried pull starting it as well still wouldn't go.... V6 2.9L...
View 9 RepliesIt's an 88 2.9 and sounds like a little diesel! The fellow I purchased it from said the valves need tightened, I thought perhaps a timing chain, but figured valves would be an easier place to start. Yet, I'm not sure where to begin? Or how tight the valves need to be, are there torque specks?
View 2 RepliesI have an 88 ranger with the 2.9l. The headlights work and the markers do to. The brights don't though. and also none of the turn signals work, the brake lights work though but i don't think the reverse do, I can't see them. Do the turn signals and brights share a fuse on there own? How to diagnose it or what it may be?
View 9 RepliesI've got a 1988 2wd Ranger with a 2.9l v6. I just recently got it running. It has been setting for awhile. I replaced fuel tank, both pumps, fuel filter, Plugs, Wires, Cap, Rotor, TPS. It ran great for about 100 miles. Then yesterday on my way to work about 4 miles down the road it started to miss/stumble especially at about 55mph while in overdrive. When I got home I pulled the codes and I got KOEO 22 Map sensor signal out of voltage(engine off), 53 TPS signal voltage to high, 95 Thermactor Air System Problem, or Fuel Pump Monitor signal, indicates circuit problem.
KOER I got 21 ECT sensor signal voltage out of range or loss of signal during normal operation or Crank Sensor problem, doesn't have a crank sensor I believe. But I did change the ECT sensor and it still stumbles and seems like it misses. Noticed it is sluggish getting up to speed kinda surges and bogs. Im at a loss it isn't showing any more codes. Checked all plug wire connections and made sure everything was making connection. The only other thing I can think of is that the ignition module on back of distributor is going bad. Not advancing the time correctly.
My Grandpa has an 88 Ranger 2wd with the 2.9l V6 and a 5 speed, I believe, M5od. I was driving down the highway when I heard a noise. I tried throwing the tranny in neutral but when I pressed the clutch pedal in, I had no pedal whatsoever. Engine took awhile to restart. It'd turn over a little almost as if a rod was bent or something of the sorts. Eventually the engine started and would stay running as long as the clutch was pressed in (disengaged).
The engine dies no matter what range the transmission is in,neutral included unless the clutch pedal is depressed. It Will die when the clutch is released in any gear with no forward movement that is noticeable. I can spin the tail shaft with the driveshaft installed and all gears in neutral but the input does not spin at all. Input shaft wont spin at all, period. I originally thought the slave cylinder was KIA but now I am very confused on what the problem could be? Is there a bearing the input shaft rides on that may of seized?
I pulled the tranny last night and took the top cover off. Yes, I made sure it was in neutral when I removed the cover. I can manually shift the collar to all gears by hand, 5th and reverse included. I'm stuck between a rock and a hard place here and where to go from here. I have bought a new clutch assembly and slave cylinder. This truck was bought by my Grandpa brand new in 1988. It has 98,000 miles and everything is original. I did forget to mention that there was very little oil in the trans when I drained it and it appeared to be gear oil vs ATF.
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.
97 ranger 2.3l ... I have a problem where I'm losing full power (like cutting out) while under acceleration it's only for a split second almost like a hesitation. I got p1443 for the first time today and I was looking at my fuel trims and I noticed my long term FT is at 99.2% and never changes while my short term goes between negative and positive no more than 6%positive and like -4% I assume this is normal for short term but I really am just guessing on that. I am thinking perhaps I need a new fuel pump...but maybe I'm wrong...truck has a new fuel filter and a new evap purge solenoid...
View 14 RepliesI 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..
My 1988 XLT 4x4 2.9L truck can't make up it's mind. Oil light comes on when ever it wants. I replaced it with a new one to make sure it wasn't bad. My lifters start clanking then they'll stop making noise when ever . Oil light goes out.Runs great. I let it Idle and once warm oil light pops on again. Rev it up light goes out then comes back on at higher rpm. Let Idle lifters clank again...and so on. seems erratic. Weak oil pump???? slop plugging pick up screen??? I'm running 20w50 oil is has 188,000. It ran today for 1/2 hour no oil light no noise then Here we go again..clanking valves ,oil light on...
View 4 RepliesI am going to fail State safety inspection due to a problem with my brakes. Months ago when I was trying to get it through emissions testing the mechanics looked under the truck to see where the brakes were leaking. All they told me was the rear lines are rusted through and need replacing.
From my reading I believe the lines are 3/16" line and I think they go around the back of the fuel tank and up the frame rail. Correct?
My questions are, what length line do I need (I am not a hard-line expert, but I will try). I want to order some ss line so it won't rust through again. Is the system made of small sections threaded together? Or is it one long section? And what else would I need/want to replace along the way?
I have a 1988 Ranger with the 2.9. 2wd, xlt. It seems that my wipers have no power. I put a test light in the fuse panel where the 6A cb is and no light. To verify I wasn't doing something wrong, I put it in the dome light and tester came on. I tried with the wiper switch on interval, low & hi. I can't seem to find where the power comes from to follow back from the fuse panel. The washer fluid doesn't work either. No clicking from relays or anything.
View 2 RepliesI have a 1988 Ranger 2.9 V6 that sits most of the time. The fuel pump quit working so I removed the bed and replaced the pump in the tank and the inline filter near the engine. I did not replace the inline high pressure pump because it still made a humming sound so I assumed it is working. Now when I turn the switch on I hear both pumps working but the truck will not start. It seems like it wants to fire or fires for just a second but just wont completely start. Is the system supposed to be primed and if so how?. I suspect a fuel problem but I dont know how to check pressure or check to see if fuel is getting to the engine. What to do next?
View 6 RepliesBackground - 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.
'86 Ranger, 2.3L, Automatic transmission.
Been having a sputtering/rough running situation once warmed up, replaced every so often with open loop smooth running. Lately, have had several occasions where the truck stalls and will not restart after a hard right turn (fuel pump powers up, tho) After 30 or so minutes of repose, truck will restart and run.
Recent History:
During the last 1-1/2 years, had cylinder head rebuilt and reinstalled. Had to run it all winter w/o EGR tube attached because of bad fitting at exhaust manifold. Replaced the fitting last spring and replaced cat back exhaust system. Had manifold hole plugged with pipe plug all winter. Have had a diagnosis of poor compression in the past, have not rechecked compression since head rebuild, but did have a noticable increase in power.
Have checked base ignition timing and it is correct. Valve timing appears to be as it should be. Have not had the opportunity to check for spark during one of the breakdowns, since I had no tools and it was night time.
The codes:
Early in Fall, got 14, 21, 24, 34. The 14 particularly interested me, as it suggests ignition problems.
Just before pulling the distributor, I checked codes again; 14 had disappeared as did 34 (EGR issues I resolved above) but I still got 21 (coolant temp out of range) and 41 (no HEGO switch) So I left the distributor alone and replace the HEGO sensor and cleared codes.
Last code check, just got 21(coolant temp sensor voltage out of range) and 24(air charge or Vane air temp voltage out of range) There is very little heat on cold days, full radiator and I've "burped" the cylinder head on an incline more than once chasing trapped air.
I'm suspicious of the TIF module, since the stalling is after warm up and self corrects. It was replaced once perhaps 12 years ago.
My 2000 Ranger standard 4.0 4x4, started spitting and sputtering the other morning just when i was gone up hills then it would quit doing it. The other evening it got to where it don't idle, missing very bad, and wouldn't even pull itself up a slight grade, and the wife said there was flames and sparks coming out the exhaust. Now it wont even try to start, it just turns over. I put a different coil pack, wires, and plugs, and still nothing. I pulled the gas line off the frame fuel filter and its shooting gas out, and I got gas to the check port on top of the engine.
