Ford Ranger / B-Series :: Intermittent Skipping / Bogging / Lack Of Power
Nov 23, 2011
My problem: Intermittent skipping / bogging / lack of power etc. It started about 2 months ago and is progressively getting worse. At first it was every couple of weeks, then once a week, now daily. It happens at variable times, temperatures (engine), and rpm's. When this happens I can pull over, shut the engine off, wait 1 minute and restart and it drives fine until next time. Now it will run fine for 1 to 2 minutes then stall. Sometimes runs rough first other times dies flat out. Starts right back up though?
What I've done so far: New plugs and wires. Tested both coil packs (primary resistance at input socket is .7 ohms on both coils and secondary resistance on top is 12.02 to 12.07 on both coils ).Since code 224 is primary circuit failure coil # 1 2 3 or 4 I replaced primary coil anyway. No luck. Removed ICM had it tested(at auto zone) 10 times in a row, it passed each time.
Checked the fuel system at the rail idles at 32 psi with vac.on at regulator and 40psi with vac. off at regulator. All within specs.
Checked compression. 170 psi lowest reading and 180 psi highest reading.All within specs.
Took some timing notes. Idles at 22*btdc after a minute or 2 it drops to 15*btdc for ~5 seconds then back to 22*btdc then dies flat out. Or it will go from 22*btdc to 28*btdc run rough for ~10 seconds then stall.
I disconnected the spout connector but it still idles at 22*btdc. I thought this would force the engine to run at base timing (10*btdc) but no go.
I'm thinking maybe the cam position sensor but I can't find it to replace it. It is not by the oil filter where it should be.
Found this info on rockledge site ("On other setups, such as the 2.3L Ranger, the PIP and CID signals are both generated from the crankshaft by virtue of a "dual vane actuator" which is essentially a doubled-up Hall-Effect sensor.")
Does this mean I don't have a cam position sensor? It's all rolled into one at the ckp? How to confirm that I have DIS or EDIS ignition ?

I just bought this truck last week. It has 55k on it, so I'm guessing it sat a lot. It seems to run great, but today on my drive to work it started having an intermittent bogging down when accelerating. It didn't seem to matter if I was accelerating soft or harder, or what rpm I'm at. It also did it when it was cold pulling off of my street and it did it once or twice after 15-20 minutes of driving. It just feels like I let off the gas for a moment, I can watch the tach drop about 500 rpm and then just as quick it picks right back up and is fine for a bit. I don't have any check engine light.

I am fairly new to this stuff but I just got a 85 Ranger 4x4 and its running pretty rough it will be fine then all of a sudden it will bog right out and want to stall so I have to keep my foot planted on the gas and it pops and spudders and eventually runs normal again? Its a 2.8 V6 carb...

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???

I have a 2003 ford ranger 2.3 vin d 5 speed, this truck originally... Took it in for wires plugs front brakes fuel filter battery and added a small cold air intake. We discovered a valve cover leak and while repairing guy drops a screw into a valve and when finished he started it lodged the screw between the valve, shearing off a cam sprocket bolt. Throwing the timing. 2 valves on the exhaust side were bent and replaced. no damage to the head.
Timing was reset and the truck was running. 2 days later truck is running/had a hint of exhaust smell then started bogging dying and shaking, at which time we got an 02 bank2 lean code and fixed that. it cleared code and didn't fix it. From there we replaced coil, imrc intake bc of a crack, tried and check all vacuum, reset the timing. Timing would slip before but no longer than 10 minutes every time truck started.
Found the hole in the timing cover that holds the bolt to torque? to harmonic balancer was broke. replaced along with the diamond washers and cam sprocket bolts. timing finally held crank sensor was adjusted. truck came home for one day running good, we had removed the cold air intake and replaced the factory air intake. next day it was so slow outta first gear, you must baby the throttle, if you floor It, it sputters and kinda pops, truck stays slow all the way to about 10 mph and 2000rpm then it begins grabbing speed, 3000rpm is where this truck shifts the best, 2nd is better, third better than that.
As rpm increase the truck runs better, it idles steady at 1100-1200rpm at stops with an audible miss and then struggles again on takeoff. Here what im wondering, the truck has an abs sensor that just came on, but no codes showing now.tomorrow I wil run matko determinator 3.0 on it. and test the catalytic converter. first how do I check the timing belt to see if it stretched? do these trucks store the p.i.d.s. koer or kams that could cause one, all, or any of this and if so do I have to have it flashed from ford or can you manually do this without a drive cycle test.

I have an 85 Firebird V6, 2.8L, tuned port injection, we bought it new and I have changed the oil every 2000 miles, it still runs great, except… The fuel pump gave out, I replaced it with a new Bosch, in the process I tried to replace the fuel filter, the line was rusted, it broke. I had to replace about 2 ft. of metal line with nylon tube, I also had to install a fuel filter with quick disconnect fittings, the filter is not the original but some generic because the original metal threaded fittings are gone. It runs great up to about ½ throttle, if I try to accelerate more than that it loses power and almost dies. If I turn off the ignition and restart the engine it runs fine for a while, full power all the way to full throttle.
I’ve noticed that if I keep the fuel tank full the problem happens less often.My theory is that the fuel pump is aerating because of not enough restriction in the fuel filter because it isn’t designed for that car, if I keep the tank full it is harder to start the aeration and stopping the pump and restarting it stops the aeration for a while. If I could get a fuel pressure gauge and be able to see it while I’m driving that would be great, but how? Also, what does the fuel pressure regulator really do? Does the fuel pump run all the time the engine is running? It also sounded like an electrical problem but it idles well and it is very smooth up to about ½ throttle. Could I just have a bad pressure regulator or does my theory sound like it makes sense?

I just totally re-built the rear brakes in my 93 Ranger 2wd. Now its seems I have this 'intermittent vibration' between 90 to 105 km/h.

My 2.3L Ranger experiences a drawn out 2-3 shift but only does it once in a while. On my drive to work it might do it at 1 of 10 stop/go and the other times it's perfect. It really seams to do it more when it's cold???? I know it's an electronic shift trans so my guess is because it's intermittent it's getting a false signal from somewhere - maybe? All of the other shifts are fine, it just happens 2-3. It has the correct fluid in the trans and is new.

Ok, basic rundown. Stop at a red light, turns green, when i go it gives a strange grindy-growl from the rear. Lasts maybe 2 seconds then its gone. its very uncommon. But it is something i am interested in getting figured out. Doesn't happen any other time, only on complete stops.

2002 3.0, 43,000 miles. Intermittent 'chirping' has begun. Is this the "wear indicator" on the belt tensioner? If so, what is it telling me? And where do I put the breaker bar to slack off tension...Red Arrow, or Blue arrow? They both look like bolts...I was expecting to see a 3/8" square opening...and do I turn clockwise or CCW to slack it all...

My '94 4.0L XLT has hesitated to start a couple times lately. Then, after sitting for a week while we were on vacation, the truck would not start at all today.

I read about the fuel pump relay, so since I am not made of money, I decided to change that first ($16 vs. $100). After installing the new relay, the truck started! I put the old relay in the box and tossed it into the glove box.
After lunch, and some thought, i decided I wanted to put the old relay back in and see what happened. Guess what! It started with the old relay as well! I also noticed that the humming/buzzing sound the fuel pump makes when the switch is turned on was different with the new relay vs the old one. I put the new relay back in, but now I am unsure where my real problem lies. Intermittent relay, or fuel pump on its way out??

I have a 2005 Ranger 4x4 4.0 automatic with an intermittent no crank, no start issue, So the problem has been getting worse over time This time when it wont start, all of the lights work, the radio, the fan, etc. They are all bright and functioning.
The battery is brand new and showing 12.9v at rest. (Yes, I have tried to jump it and charge it to be sure). However, The gauges are not functioning when the key is turned. I have no click, the lights don't dim, nothing happens when I turn the key.
Another neat point, if I turn on a directional with the key on, the relay clicks so rapidly that it won't even flash the lights. I am assuming that it is a ground someplace, but I dont even know where to start on this truck.

This has happened maybe 3 times in the last month. Once merging on to the freeway. Another while cruising 70 in the carpool lane. And the last one I was leaving the job site and it did it.
What I'm talking about is a quick like cut out or stall. Maybe a second of time then back to normal. It also makes a clunk sound. You know these things are hard to describe.
Just don't want to freeze up on the freeway and cause a wreak. Also can I tell from my vin.# if I have limited slip or posi.

Im 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?

Previously on "This Old Truck": [URL] ....
Mileage now 298,5xx. Done since last report: Oil change and filter. Trans oil change (merconIII, no leaks apparent). Tires. Front brake pads. Clutch safety switch (was interfering with cruise control operation) Coolant replacement. (see below)
Rat damage related overheat (near total coolant loss, but no MIL) at 288k. (Rat suffered acute lead poisoning later that night) No sign of rodents since.
Fuel filter change (after onset of symptoms).
NO MIL/CEL, no pending codes. CEL/MIL operates on KOST.
Temps normal (190F +/-2 deg during steady-state cruise operation, fuel flows and fuel mileage have not changed significantly. (fuel mileage has IMPROVED approx 5%, possibly due to gentler/slower driving)
M5OD with Limited slip 3.73/ payload pkg II (1650lbs)
Symptoms:
- Intermittent misfire on startup, seems to get better as the truck warms up. (intermittent= some days it do, some days it don't.)
- Truck starts and idles well, even with misfire.
- Intermittent loss of power, usually worse on days when no- or minor- misfire at startup/cold idle. From the driver seat it feels like accelerating over painted lines on a rainy day. . . a couple revs of no power, then it pulls hard for a second or two, then misses a couple of shots, lather, rinse, repeat.
- Usually worse in higher gears; (not noticeable in first or 2nd, bad in 3rd at high power settings, now almost constant in 5th, to the point that truck will not accelerate below 3000rpm in 5th even on flat ground.)
- Fuel flows above 4GPH/ OBDII "LOD" (engine load) reported above 75% are typical during malfunction. (Fuel flows have been as high as 9GPH with no problems on other days.)
Symptoms started at approx 292k and have been slowly getting worse over the past few months. . . . usually worse at beginning of trip, fading to very occasional after 50 miles of high-speed driving. Some days/trips no noticeable malfunction.
Thoughts:
1) Ignition wires tired? (did visual inspection, no obvious damage, but no water spray test performed, but seems likely given that the problem is most evident in conditions that would lead to high cylinder pressures.)
2) Fuel pressure? (not measured yet. . . original pump but possibility discounted due to intermittent nature of malfunction.)
3) O2 sensors tired/rat damage? (Original units still installed/ no obvious damage on cursory visual inspection under truck)
4) Injector going bad or injector wiring rat damage?
5) Plugged catalytic converters? (no sound of blown exhaust gaskets, exhaust flows well at tailpipe, with puffs at misfire.)
6) Cam sensor? (never been replaced; known issue with this model engine. Had intermittent mystery squeak that came and went at approx 250k-260k)
7) Clutch slipping? (never had one do that; always lose the throw-out first)
8) LSD problem? (fluid level/ appearance ok, last changed 150k; would expect worse in LOW gears)
9) Blown head gasket/s?
10) Cracked heads/ block? (Oil and coolant levels and appearance normal)
So: That's the plan of attack. What am I missing? (Clutch last done approx 170k; burned throw-out, did disk, flywheel, pressure plate, slave cylinder while the trans was down. I did not open the hydraulics or disturb the pedal linkage when I replaced the safety switch. )

I bought a used Ranger a couple months ago and it ran fine when I test drove it but a week later it started having a misfire every now and then at idle.. I must have gotten pretty unlucky with the test drives..
The misfire comes and goes, it will run fine for a week or two and then it will misfire at idle for a week or two. It only seems to misfire at idle, the truck runs rough/shakes but once you give it a little gas and start moving it goes away. Usually it has a check engine light on from startup when it's misfiring and it goes away on days that it's running fine; it will occasionally misfire at idle with no check engine light. Sometimes when its running really rough the CEL flashes while it's misfiring at idle and I've actually restarted it real quick and the misfire went away for a bit. The engine codes that come up are misfire on startup and misfire on cylinder 4.
I've tried cleaning the MAF sensor, replacing the fuel filter, testing for spark and compression. Compression was 150-155 PSI on all cylinders, however, the compression on cylinder 4 is different depending on whether the truck is running well or not. When it's misfiring the compression on cyl. 4 is 90 PSI and when it's running fine it's 150 PSI. I'm not sure what could be causing intermittent low compression like that?

2001 3.0 XLT Ranger 2wd 4 door
Okay getting ready to trade in my Truck. So I removed all the extra things I put on there while I was in college, the amp, fog-lights, and analog oil pressure sensor along with their wiring. It was pretty easy minus removing the oil pressure sending unit part.
I had to unplug the MAF to move the intake out of the way while I was repairing a loose vacuum tank. But I forgot to plug it back in when i closed everything up. I started the truck and drive it about a half mile before I was able to pull over and plug it back in. Truck ran and shifted fine after that, but the CEL came on. P0119 Coolant Temp Signal Intermittent. Guy at Autozone said it was Intake Air Temp Sensor intermittent and I could just replace the part, but they were showing a separate part even though it is built into our MAFs.
So now the CEL is on, can get it to go away. Truck is a little jerky every once in a while, like a misfire, when between 50 and 60. Before all this the CEL was off. Now after I cleaned it up and removed some of the superfluous accessories, I get a CEL. I wanted to trade it in this coming weekend without having to take a loss because of the CEL or spend more money to fix it.

My 6.0 with 178k on it just started to have issues today. Low power. When I hit the pedal hard the motor revs and the truck barley moves. When I baby it it goes up to speed and shifts fine. Overall lacking power and not going anywhere. No CEL on. Turbo spools and seems to be ok.

I have been thru everything i can think of except the main ECU on the ranger.
I've replaced the starter as well as the starter solenoid also the ignition switch.
What is happening is there is no power after the main wire to the solenoid from the battery. it doesn't power up anything. I've checked the fusible link and it appears intact. with a test light i can see that i have no power from the ignition itself i guess to tell the solenoid to work. i have noticed that the ignition cylinder is a little loose but what can cause there to be no power at all?
Could it be a bad solenoid?

I just was given this truck the fuel pump was wired directly to the battery I ran new wire to a new relay to fuel pump using a toggle switch to turn the pump on. Now I'm getting no power to the fuel injectors does the pump relay also send power to the injectors.
