Ford - Ranger :: High Idle - Pickup Occasionally Go Into Over Drive When It Is Not In Gear
Feb 18, 2014
For about 6 months my 95 ford ranger 2WD 4 cylinder pick up has occasionally gone into "over drive" when it is not in gear the idle will get crazy high, like one of those party toys that yo blow into and it spins an makes noise. Once put into gear it calms down but it has more forward motion without gas than before. If it gets really bad at stop lights I will turn it off and turn it back on. It may still do it when I turn it back on but by then I will be putting it in gear. When it is in this condition and I turn it off it takes longer to turn off, like it is winding down.
I would say that this happens every 4th time it is drive, sometimes less sometimes more. There seems to be no rhythm. I took it to an electrical specialist and they could not find anything, and last week the check engine light came on so I took it to our normal mechanic. They did a test and found that the engine speed limiter had been reached which was why the check engine light came on and also pretty scary. The diagnostic codes were P0500 and P1270. I am worried 1. that this is making the care unsafe to drive even though it seems like we can manage it to a degree and 2. that is is doing damage to the car by putting it in such a hyper work mode.

I've got a 99 Ranger. A month or so ago, it started to be a little hard to start. It would turn over, but not fully start unless I gave it a little gas. This did not happen all the time, primarily it happened after it had sat all day when I left work. Not long after that started, my check engine light came on. The codes were for a lean mix as reported from the 02 sensors. Before I could dig any further, it just wouldn't start at all one evening. This was after I had driven it for 30min and then parked it for an hour or less. But this time it was different in that the solenoid would just click, but that was it, like it didn't have enough power to turn over. I took the battery to have it tested and it had been severely discharged.
I got a new battery as that one had reached it's limits. Put it in and the truck started right up no problem. A few days later it started acting up again like it had originally, I had to give it some gas to get started. I had the alternator/starter checked, both were fine. A day later, it got so bad that I had to shift to N and keep giving it fuel anytime I stopped the truck. I had to do this all the way to and from work. Now this morning I go out and it starts right up, no issues, no dying at idle and didn't have bit of problem coming in. Initially we thought it must be a fuel pump, but then I can't explain why it worked fine this morning. I changed the fuel filter less than 2 years ago, so I wouldn't think it would require changing already. Wondering if there's a sensor issue, one that calls for appropriate amount of fuel?

My M5OD in my 1999 Ranger 4x4 with 3.0 occasionally pops out of 3rd gear. I think it does it only under light throttle or coasting. Also some vibration, especially in 3rd gear. Once in a while the gears grind when shifting into third. Truck has 145,000 mostly highway miles. Frequent fluid changes with Redline D4ATF.
What could be the cause, bad synchros ? How hard is it to remove the transmission and make a repair for something like this, what kind of special tools, etc. I assume a transmission jack would be real useful, what else would I need other than the normal wrenches and sockets ? Is there a good shop manual recommended for doing this repair ?

So, in my 99 Bounder RV (F53 chassis), V10
I think it has a 4R100 transmission in it (I have not verified this).
I had the oil and filter changed about 10K ago.
Runs and shifts fine .... then I stop and idle with it in gear (say stopped in traffic for a few minutes).
Now the thing shifts super hard! I actually get rubber in all gears.
So I pull over, shut it off. Restart the unit and everything is fine again.
It does this very consistently!
I went to the local transmission shop. They said with 110K in an RV it could be anything and I should think about letting them rebuild it.
Now that is something I would do ... not diagnose a problem and just rebuild it. I thought a "professional" would actually look for the problem first.
I don't want to rebuild the transmission if there is small item that will fix this.

My gf's dad said I could have his 07 Ranger 4.0 2wd with 230K on the clock if I fix the tranny 5R55E. One day he was driving home and all of a sudden had no drive. The tranny will run thru drive, neutral and reverse, but has no drive to it. Engine revs with nothing to show.
Tranny fluid was very dark and pan had nothing but the usual "metal flour" in it. I stopped there, did not pull the filter or anything else.

I have a 98 XLT 4.0, auto trans with 109K miles and when it's really hot outside and it's been driven when I start back up and put it into drive it sometimes takes a while to go into gear. A friend says the transmission fluid doesn't look too good and it smells. Obviously I have a transmission problem but my question is would changing the fluid do any good at all? Since the tranny is bad what harm could it do? The fluid was never changed previously.

The trucks seems to Idle Rough in Park and Drive, Cold or Hot. It mellows out as soon as I give it gas but at stop lights or in park it goes back to a seemingly rough idle.
This is my first Ford Ranger and dont know if its normal. No code or dummy lights.
2007 2WD 4cyl

1996 Ranger 2.3 140 CID XLT 126,000 Miles. When coming to a stoplight or stopping the engine idle is low and causing engine to almost die. Engine has been stuck at high idle a couple of times. It started with the engine idle slowly coming down and now it its too low. I suspect the Idle air control valve.

I have a 99 Ranger w/3.0. It idles about 1500 rpm cold,and 1200 warm. Here are the things that I have tried.
1.Checked ALL vacumn hoses/lines
2.Changed Air idle control sensor
3.Throttle position sensor
4.removed and completely cleaned throttle plate in throttle body.
5. removed top of intake manifold and checked for cracks and/or leaky gasket.
Nothing seems to change. Could it be a faulty ecm?

The accelerator pedal on my 1993 Nissan pickup occassionally "sticks". Mainly when I'm leaving a (stop-sign/red light, etc) or if I let off pedal (in traffic etc) then push on it again to accelerate. I've changed the throttle cable (had a brand new one from brother in law...still in packing). I took it to Nissan dealership few years ago and they couldn't figure it out, same with a (highly recommended) local shop.

I have a 1995 ford v6 4.0L with a 4R55E transmission, and 3.27 Non-LS axle. So Im guess the 2H (high range) is the 3.27 Gear ratio. But in 4L (low range) whats the ratio?
And pew lol this rangers 4wheel drive is a beast went through a crap load of mud yesterday which also brought me up to the question should i be using 4L or 4H for that?

The revs surge from low idle to high (about 1000 rpm) every few seconds, but only when the truck is in gear,and the AC is on. What it could be. Also is it something I could fix myself? I have been driving with out the AC for a while but going into summer I need it on.

My 92 ranger, 2wd, 6 cyl, manual trans, is running at about 3500 rpm at idle. I was wondering what might be the cause, maybe something with the throttle or could the gauge be screwed up.

My ranger 2.9 automatic 2WD has an high idle when started for about 6 min, engine can be hot or cold, still get the high idle, then it will drop to around 900-1000. I've changed the Idle control twice, checked EGR function. Replace temp sensor. Disconnected battery for 15 min. No code output.

My truck has been doing this since I got it and I can't figure it out. It's a 2000 Ford Ranger XLT 2.5 5Spd. It runs fine if you don't rev it above 2500-3000 rpm. After you rev it that high coming down to idle it is stumbling real bad and sometimes stalls. I've been driving it like this since I got it, and it does fine other than this. It gets better the longer you drive it, but it still will do it if you rev it high enough.
Here are all the parts I personally have changed (previous owner said he did the plugs and wires and air filter, which it looks like he did but I'm about ready to change them myself):
-Fuel filter
-coil packs
-timing belt
-egr valve
-cleaned throttle body
-iacv
-tps
-thermostat

Ranger often wants to idle at 2,500 to 3,000 rpm. I'm glad its got a clutch! This is a long term intermittent problem that is getting worse. I have replaced the the IAC twice. I have unplugged the IAC when the engine is in high idle and the engine idles normally. But, starting the car with the IAC unplugged makes car run rough. That makes me think the IAC is not getting the right voltage input from the pmc (eec). Mine is a 2002 with the 3.0 engine. Throttle plate seems to be closed.
What sense inputs does PMC use to determine idle air position? Also replaced TPS sometime ago but that didn't work either. Sometimes turning off the a/c will knock the idle back to normal but not always. Turning the car off completely usually resets idle. But the high idle comes right back after accelerating. Drove the car today and idle would stick and stay high when clutch pushed in coming to a light. However. as the car slowed to a stop the idle would come down when rolling 1-2 mph. ??

1999 B3000 with a 3.0. The truck idles at 850rpms. When it starts it idles at around 1000 and runs very rough. When I disconnect the IAC the engine dies. The AC also has problems it blows cold at idle but at highway speeds after 7-8 minutes running the compressor kicks out. One can turn it off and it blows cold again after a few minutes.

I have 95 ranger 3.0L revs up over 2000rpm at startup then comes down slowly to a little over 1000... Changed the IAC valve still does it... When I let it warm up I unplug the IAC and idles normal and smooth about 750 RPM so I don't think it's a vac leak... What else could it be???

Truck is a 2003 Ranger EDGE 2wd auto w/140K miles (looks new) that was a one owner truck I recently bought. Came from Texas and is clean and was well maintained I got all service records up until I bought it in the fall last year. OK now the problems...
First...it has a high idle in the mornings when cold about 2000RPM. After it warms up it settles to about 800-900RPM but is VERY ROUGH to the point where it feels it will stall. I DID replace the spark plugs and the plug wires look newer and are not OEM. I DID remove and clean the IAC and it does not look very dirty but I did slightly clean it anyway.
When I did this I disconnected the battery for 20min. After I put it back together it ran smooth for about the first 10 minutes then same rough idle came back. I was told this truck has no EGR so that's not an issue. There are NO CODES and when I ran my pocket scanner nothing comes up either. Should I just go to NAPA and get a new IAC anyway? What else can I do?

My '03 Ranger is having a high idle problem. It's a 3.0, manual, 2wd, 141,000 miles. When it's cold it will idle at about 1500 but once I drive it, even just to the end of the block, it will idle at about 3000 and shoot up towards that between shifts. At a traffic light it will idle at 3000 and maybe go down to about 2500. If I bog it down with the clutch it goes right back up once I put the clutch back in or put it in neutral.
I replaced the IAC, no luck. I cleaned the MAF and checked the voltage on the TPS and it is good. I replaced the PVC valve, but the old one was fine anyway. I've sprayed around with carb cleaner and don't notice any difference. I've plugged it into my dad's AutoTap which lets me monitor everything on my laptop and the only thing I can see that looks suspicious is that even with the engine off, the Absolute Throttle Angle reads 18.8%. If I step on the gas with the engine off it goes up to 91.8% so I would imagine that just has to do with the function of the TPS and probably isn't out of the ordinary, but I don't really know what that number means or what the Absolute Throttle Angle is or is supposed to be.
Short of taking the intake plenum off and physically inspecting it for cracks, I'm stumped.
