Ford Ranger / B-Series :: 1990 - Rough Idling / Truck Dies

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.

Ford Ranger / B-Series :: Sputtering / Rough Running Situation Once Warmed Up

'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.

Ford Ranger / B-Series :: 2000 3.0L - Idling Rough / Hesitation While Driving

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.

Ford Ranger / B-Series :: 2004 - Hard Starting / Rough Idling / No RPMs

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?

Ford Ranger / B-Series :: 2006 XLT - Vibrating Hard / Rough Idling - CEL Is On Solid And Not Flashing

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?

Ford Ranger / B-Series :: New Plugs Now Truck Running Rough

Although my lil' truck (2006 Ranger XLT, 2WD,with 4-cyl / 5spd, and 115K miles) has been running just fine since I bought it about a year & 5K miles ago, I suspected it still had its original spark plugs and I figured I should change them before problems arrived.

As I suspected, the plugs that I took out looked to be original. I measured their gap and they all had excessive plug gaps - around 0.052" gap. I installed the four new AUTOLITE APP104 (double platinum) and checked their gap, and they were a bit tight at 0.042". My book says they should be at 0.044" gap. But I installed them at 0.042 anyway, figuring they'll burn wider in time.

One by one, I smeared a small bit of never-seize on the plug threads & at the plug-to-cyl head tapered edge. I smeared a dab of Dielectric Grease around at the top of the plug to ease the plug wire re-install and hopefully calm any possible arching. The plug wires came off the plugs easy enough and went back on just as easy.

I hit the key and the engine fired right up. It idled rough as expected. However, it continued to idle rough and if I raised the RPM level, it would respond, but still ran rough. It is throwing a 'Check Engine Light' on the dash cluster now - whereas it wasn't prior to the new plugs.

Ford Ranger / B-Series :: 2003 Truck Idles A Little Rough - Code P1450

Where to start looking to resolve this code. It is not an intermittent code. It returns after about 3 to 4 key turns. Truck idles a little rough but runs fine. I have looked up the code and causes but wondering how to deal with this directly and fixed it. I'm wanting to sell my truck for something bigger and would like to solve the issue before hand. 2003 Ford Ranger Edge...

Ford - Ranger :: 2008 - Intermittent High-pitched Squeal After Warmed Up / Idling?

I have an '08 Ranger, automatic. For the last several months, the truck has been making an intermittent high-pitched squeal/whine, but only after it has been warmed up (10--15 minutes driving) and only while it is idling. As soon as I'm driving, the whine stops; whine will occur both in drive (but stopped) and in park. The whine will not happen every day I drove, nor will it happen at every stop. When it does squeal, the squeal will fade in and out in volume.

An interesting kicker I've found recently: it seems to be dependent on electrical draw. For example, if I'm sitting idle with the lights on, and the truck is squealing, and then I turn the lights off, it suddenly squeals less. Still squeals, but less than with the lights on.

I have had mechanics check all the usual suspects, belts, etc, but have not found anything amiss. Nor can I actually get the squeal to occur when I visit the mechanics.

Ford Ranger / B-Series :: 1995 - Bucks Sometimes When Warmed Up

I have a 95 Ranger that when warmed up completely will buck when I let off of the gas. It is a 5 speed and this problem really only happens in 3rd gear and also have noticed it doesn't happen in 4WD. When the engine is cold and I am driving and let off the gas, the truck coasts smooth as silk and as it warms up, there becomes a louder thump when the gas is let off.

It will not do it all the time and it really only happens in third gear at low RPM's coming to a stop. I can give it gas and it picks right back up normally, so I doubt it is a misfire. Also since the truck is a 95 I do not have any CEL indicators, nor is there even a CEL light built into the dash in the truck. It isn't a huge issue because I am used to it and can drive it accordingly without having a problem.

Ford Ranger / B-Series :: 1985 - Chattering At Startup Which Quickly Went Away After Warmed Up

My ranger has always run pretty good except for a small bit of chattering at startup which quickly went away after it warmed up. Now all of a sudden its much louder and doesnt seem to go away while driving. I read about the oil pickup tube getting blocked and not properly delivering oil and so I performed the superhuman task of dropping the oil pan to check. While I couldnt get the oil pan all the way out, I got it to where I could feel the oil pick up screen and everything seems okay. I have the valve cover off. Are the lifters adjustable? Whats the issue?

Ford Ranger / B-Series :: Warmed Up While Driving - Fluid Leak From Front Of Transmission

I bought a 1990 ranger with only 38000 miles on it from a online auction from boing aircraft. it never left the flight line and never even had a title. I picked it up from the airport and found out that it didn't have AC like they said, I was a little ticked but that isn't the main problem. When I drive it and it gets warmed up it leaks Tranny fluid from the front of the transmission. The engine does not overheat. It is a 4 cyl AOD automatic with a real thin radiator and a transmission cooler. Without AC the truck isn't the good deal I thought I was getting, and with a bad tranny this is becoming a big OOPS. Why this is happening?

Ford :: Ranger 1999 - When Truck Is Idling RPM Will Drop Down Very Low

I own a 1999 Ford Ranger. About two weeks ago, the engine started acting up. While the truck is idling, the RPM will drop down very low (like .5) and begin to sputter, then shoots up to about 2-2.5 RPM, then back down to .5. Sometimes it will drop so low that I have to give it a little gas to keep it from going dead (which it has a few times).

The motor has around 150k miles I would say (engine was replaced a few years ago, so the odometer shows higher than the engine). My water pump is also going bad, but I am having that replaced this weekend.

Here is a link to a video I did so y'all can hear/see what's going on [URL] .....

Ford Ranger / B-Series :: 1988 - Overheats While Idling?

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?

Ford Ranger / B-Series :: 1987 - Stalls Out While Idling?

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.

Ford Excursion :: Rough Idle After Truck Has Been Idling For A While 5 Minutes Or So

2005 Excursion v10 137000 miles I am experiencing a rough idle only after the truck has been idling for a while 5+ min or so. On cold start warm start doesn't make a difference truck runs perfectly until it's been idling for a few min then starts a looping idle tach drops down to around 4-500 rpm motor sounds almost like a misfire I can press on the gas and it sputters up until it's running over 1200 rpm then smooths out and runs perfectly until it's allowed to idle for a few min then just repeats no codes are present no check engine light at all

I changed out plugs and coil packs at 100000 miles roughly year and a half ago (motorcraft parts) problem started just recently I have double checked all connections are good at plugs and at fuel injectors from what I've read up on from this forum it sounds like I could be experiencing an IAC issue or possibly an EGR issue I have checked all the rubber hoses associated with both systems and all are in good shape hold vacuum as they should are there any tests that I could perform on the IAC or the EGR to determine if it's one of those I'm trying to avoid throwing parts at it if possible, or is there anything else that I should be checking oh also cleaned the mass air flow a few days ago no changes

Ford Ranger / B-Series :: 1995 - After Warm Up Starts Idling - MAF?

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.

Ford Ranger / B-Series :: 2004 - Heater Won't Warm Up While Idling

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...
