Ford Ranger / B-Series :: 2000 3.0L - Idling Rough / Hesitation While Driving
Sep 17, 2012
Finally back able to start working on the Ranger and have a few questions.
When I got this thing back from my son it was running rough. I've fixed all the codes it was getting so no luck there now. Not sure how to explain it but, it feels like it is cutting back when driving at a steady speed and it idles rough. Not really like a miss but more like a hesitation when driving.
I've cleaned the MAP and IAC and changed the fuel filter. I also pulled the plugs and they looked good. My son installed new plugs and wires but he used the E3's and not sure how, or if, you're suppose to set the gap. I haven't checked the PCV yet because haven't figured out how exactly you get it out without pulling the intake.
So, where to look next? I'm kind of thinking the cam sensor but think I'll leave that to a shop sense I want the shaft replaced at the same time.

Ok, I replaced the head gaskets on this truck a couple years back and now I am having symptoms similar to the ones I was having then. I am not entirely convinced that this is what is wrong however.
Symptoms:
Truck was idling rough until it warmed up
Truck takes forever to warm up or simply does not warm up
If/when it warms up it operates at higher than normal temp/almost overheats(it hasn't overheated yet)
Heater blows very cold air
White smoke(has been cold outside so not sure if due to temp or coolant)
Overflow bubbled when I shut the truck off, but it has only happened once so far
I am kind of at a loss, but like I said am suspicious of the head gaskets.

1990 Ranger 2.3L 4 cylinder. The truck idles so rough it dies. It runs fine going down the road it just seems to "load up" at idle. I know there are hundreds of things that it could be, I just hate to start throwing parts at it. It is definitely running rich at idle.
It is one of those trucks that we have replaced a lot of parts. The scan tool said something about setting the timing??? Is there a way to set the timing? There is no distributor, and it is the one with 2 coils and 8 plugs.

backed out of the garage fine later in the day went to put it away started hard would not idle and only rev to 2500 .cleaned map sensor,egg valve tested and it works.cleaned the IAC and that works ,fuel pressure is 58psi. starts hard it would idle now it doesn't dies, no code . with 58psi could the pump still be bad? it has 18 pounds of vacuum. where is the vacuum line for the fuel pressure regulator on the motor?

My 1999 ford ranger, when started, shakes and then while i am driving. my check engine light is on and reads a #3 cylinder misfire. I have taken it somewhere to get it checked out and they can't figure out what is wrong with it. this problem only happens 50% of the time. I don't know what to do. Also just got a tune up.

I have a 2006 Ranger XLT 3.0 that is vibrating hard/rough idling, cel is on (solid, not flashing), has trouble accelerating with pedal punched. Will sometimes get a sudden burst when pedal is punched with rpms going up but most of the time no to slow raise of rpms with pedal engaged. Hooked code reader up to it and read ignition coil. Replaced the coil and changed plugs and wires. Truck still not running right. what gives? Is this a fuel pump, cats clogged, cylinder issue?

I have a recently purchased 2000 ford ranger 4X4 with approx. 130,000 miles on a 3.0L. When I bought the truck, it was running rough while in gear at idle, after first putting it in gear, and when coming to stops, then it quit running all together. I started by replacing plugs, wires, and ignition module. I finally got it to fire up after that, but instantly noticed the tell tale white smoke from the exhaust. Needless to say, my oil looked like chocolate milk. Rather than having the heads machined and checked, I opted to purchase a new set of cylinder heads from Dover cylinder head.
I got those on this week and she fired right up. After a few oil changes to eliminate the residual coolant from the oil passages, she still starts and runs fine, although the idle is a bit rough while in park. When I place it in gear the idle gets a little rougher. After a quick trip down the road, I'm noticing a pretty solid shudder when coming to a stop, almost like it's stuck in 2nd gear, but I can't really tell for sure. Seems to shift fine going up through the gears, but coming down is when the issue is.
I believe I'm dealing with two separate issues, one being the rough idle upon startup that doesn't seem to go away, and two being the rougher idle upon stopping. I've read everything from EGR valve, idle air control valve, low fuel pressure, and a laundry list of other things, and I just don't want to start throwing money away chasing my tail.

2000 4.2....Last year I had to replace the coil pack when it started running rough and had a code for a misfire on cylinder 3. It is doing the exact same thing now, same code, same cylinder. Is there something wrong that is causing this?

That's the best way I can describe part my latest problem. If I'm stopped at a light, a lot of the time it almost feels like it wants to stall when I first pull out. Then, it seems like it is shifting funny at certain speeds like the transmission can't decide what gear it wants to be in. Tends to do that about mid acceleration (don't have an rpm gauge to look at). At idle it seems to run fine. BTW, engine also runs rough with the ac on.

My ranger is an 89 but it's got a 91 motor in it, 2.9 V6. When I accelerate it hesitates before actually accelerating which makes me think the TPS is bad. Probed and tested and I got .85V throttle closed and 4.65 at wide open. Specs call for .8V - 4.5V
I'm not sure if there's an allowance of fluctuation, but is that high enough to point out a bad TPS? If it's not the TPS, is the ignition timing off or what else could it be?

My 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?

so I have a 1987 2.9L Ranger that likes to stall out when its idling after reaching temperature. Ive replaced all sorts of sensors (IAC, Coolant Temp, and PCV) and so far no luck. I was trying to figure out what the relearn procedure was for the IAC or get an input on any other possible sources of error. I haven't changed TPS yet.
What the engine does is when it gets up to temp, the engine will start to loose speed, and will start to shutter. Then it'll kick back up run fine for a few seconds and drop again, it'll do this for a few minutes then completely just choke out.

I have a 95 4.0 EFI inside of my 83 Ranger. Once the motor warms up, it starts to have an idle issue. I have to press the gas, in order for it not to cut off. Here is a video I posted a while back. A person suggested that it could be the MAF needed to be cleaned. I did that, and it did not work.

My '04 Ranger has over 240k on the odometer. Runs great and has never given me any issues. Everything checks out OK - all the fluids, filters, and whatnot are in good shape. No CEL or any other indication that anything is wrong (except for maybe the IAC valve and clutch slave.)
I've noticed, though, that when I fire it up in the mornings to let it warm up while I scrape the ice and snow off the windows, the heat/defrost will not blow warm air. It doesn't matter how long I let it sit, it will only blow ambient air through the ducts.
When I get going down the road, however, the heat kicks in, after a bit, and works very well!
I've not found anything that would indicate an issue with the blend door or any other component and this is the first vehicle I've had that did this.
Is it normal for a 4.0 SOHC Ranger to do this? Or is there something I'm missing?... It's not really that big of a deal, but I do find it a bit odd that it would do this.
I mentioned the IAC above - I think it's "sticking" every once in a while and, when it does, I'll hear a loud "thump" right before it idles down to around 1k rpm. I can't see how this would affect the heat, though...

My 1989 Ford Ranger 2,9 V6 is acting up like crazy (engine hesitation) after kick down (it has an automatic transmission).
It can run like a charm for days and days and for the longest drives, but if I do a kick down it will start acting up (while both cruising or idling). This is making it almost impossible to drive as it looses speed. Only way to accelerate again is to do another kick down (then it will accelerate smoothly for as long as I keep my foot down), but that is really no solution as it will accelerate way past the speed limits and the mpg is horrible going up and down like that.
A couple of times this problem has seemed to solved itself after a while of engine hesitation but normally it would be acting up for the whole drive. On the other hand it will be okay again the next time I take it out for a drive.
Diagnostics: It has nothing to do with the temperature of the motor as this will happen after a kick down on both a cold or hot engine.
Simple solution so far: Avoid kick down!
What I have done so far: I have changed the spark plugs, the plug wires, the distributor rotor and the distributor cap with no luck.

I have a 85 bronco 2, but i have no luck with responses in Bronco 2 forum, so here goes. It is the 2.8 carb, manual trans with 109K miles. Idles really well some hesitation when taking off but really bad miss and not power under acceleration. KOEO codes are 31 and 84 CM code 18. I have plugged the vacuum line to the EGR and have noticed a dramatic difference. I have tried to rev the engine and check the vac line to the EGR but I do not feel any vacuum, and at idle the vac line on or off doesn't change things. Any recommendations to whether it is the Sensor or the valve itself and what gives with the 18 code. I am hoping to have timing checked by the weekend.

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?

So among the other annoyances my 92 Ranger 4.0 auto has it has a hesitation before it starts spinning the tires under full throttle from a dead stop. It's the 4.0 automatic. I thought it would have more power than it actually does being use to a 2.5 auto. But this 92 4.0 runs and drives good. I've gotten it tuned up with new motorcraft wires, plugs, new coil, fuel filter, fuel pump assembly, fuel pressure regulator, air filter, idle air valve, new O2 sensor, new Dynomax muffler. I can't find any vacuum leaks. The engine idles slightly rough after you start it up from it sitting for a few hours, but quickly smooths out as soon as you start driving it.
This one here has no EGR. Transmission feels good, may have even been replaced by previous owner before we got it. It shifts good and the fluid is clean and the transmission is the cleanest part under the whole truck. No way of knowing for sure. The truck currently has 111,000 miles and I did all that stuff when we got it at 101,000 miles. So what could it be? I'm thinking a lazy injector or could it be the catalytic converter? Or could it be the throttle body? I know I once had a BBK throttle body on it and it made the world of difference in off the line power but it kept throwing too rich/lean condition and a TPS code so I had to return it. It sucks because it did wake up the motor. I returned it and since then the Check Engine Light hasn't come back on.

I have a 2001 Ford Ranger with stalling problems. Recently I have narrowed the range of possibilities to a fuel delivery problem. The truck has 85,000 miles on it and I had the fuel pump replaced about 10,000 miles ago, the fuel filter was replaced at the same time. The stalling usually happens after it has run for a while and can happen while idling or driving at any speed. . .whenever it lacks fuel. It will restart and run ok for a while after if you leave it alone for a half hour or more. Over the last few months it has happened with greater frequency to the point where I am currently not driving it. I can get it to stall in my driveway by letting it run for ten min. or so. I am getting two computer codes: PO 402 and PO 453.

I have a 2001 Ranger edge edition with extended cab, 3.0L engine, auto tranny (I believe it is a 5R55E) with 95000 miles. I am currently having some rough shift problems going from 2 to 3 and 3 to 4. I had the transmission fluid exchanged and it solved the issue a little bit but it hasn't gone away. It seems to rev up a little then shift real rough. I have read hundreds of threads that talk about the Valve body gasket blowing out on these trucks so I was wondering if this description matches that fix (The OD light does not flash when this happens).
I had to have the PCM replaced right after I bought it to get the emissions to pass (codes wouldn't set) and in the process cleaned all my ABS sensors, replaced my Speed sensor on the rear differential and replaced both rotors.Are there some home diagnostics I can do to narrow down my search for the problem? Also, on a different note, my father has an 03 with the 4.0L SOHC in it and it seems to get a heck of a lot more get up and go. I understand it is a larger better engine but what I am experiencing seems very sluggish for any V6. Could they be related? Might it just be a fuel filter?

My daughter returned from college with her 2000 f150 4.2 idling and running rough on acceleration. It is throwing a P0171 code only. I replaced the isolator bolts/plenum gaskets four years ago because of a P0171 & P0174 codes.
So far I have replaced the MAF, new PCV valve and elbow, checked all obvious lines for vacuum leaks (though I suspect a leak somewhere still). Also, a quick check of the plugs show some lean color/deposits on the drivers side only. Any thoughts or troubleshooting I should try next?
