Ford :: 1993 - Idling At About 3000 Rpm
Mar 8, 2015
so i've been slowly fixing up an old conversion van i recently got (1993 ford E150 5.0L).... and i'm having problems with this thing idling at about 3000 rpms... i've changed the upper intake gasket cause it was leaking, valve cover gaskets,TB gasket, IAC gasket, park plugs, wires, distributor cap and coil... i've checked vacuum lines, vaccum leaks, still no change...
When i unplug the IAC it idles down to where it's supposed to be..... so i thought it was faulty, and bought a new one....still no change... idles around 3grand unplug it and it idles down..... the IAC is getting 11.44 volts to it which is in the good from what the haynes book says.... before i changed all the gaskets it was idling around 2grand or so, and it got worse after i changed everything.

1993 5.0 mustang. The car wil start but will not stay idling. if the accelerator is gunned, it will run. The car has been tuned up (cap, rotor, plugs, air & fuel filter, also oil and filter). We thought maybe the fuel was old as it had been sitting for a few months so we drained out the old fuel and put in some fresh gas...Still the same issue. Got ahold of a fuel pressure tester from the loaner program at Autozone. The guy behind the counter looked up the spec and said it should be between 35 and 40 PSI. After putting the gauge on the Mustang, we got a reading of 30 PSI. Would this reading cause the current issue? Is a new fuel pump in this car's future?

I just purchased a 93 escort sedan 1.9 ltr engine. Car runs great when idling but bogs down when accelerating to the point it almost stalls out but doesn't stall. the car sat for a while 6 + months. We thought the gas might be bad so we drained the tank filed it with premium to run thru the line but that didn't work. thought maybe o2 sensor, changed that but didn't work. getting error codes 412 and 538 but can't find any info on these codes.

I have a 1993 Dodge Stealth (3.0 V6 SOHC) that has been idling a little rough, especially when the a/c is on. It was suggested to me that a dirty throttle body could be the cause, so I cleaned it. After I did that it ran great with the exception of idling around 1000 RPM instead of the usual 300, then the next day driving home from work (ran fine on the way TO work) whenever I tried to coast or engine break my engine began to shudder and run really rough! what could be happening?

I have a 93 Corolla LE and in October I was driving in heavy rain and the car died. Since then I have replaced the spark plug wires, plug seals, distributor cap, battery, and rotor. The car would get me from A to B, but I would always have to put it in neutral at a stop to keep it from dying. This past week we've had a lot of rain and it's been really cold so my car has been dying when I slow down or stop. I gave it plently of time to heat up thinking it would work, but it died three times on the way to work.

The 93 Cutlass Ciera 3.3 6 cyl. is hard to start..takes like 3 tries to start it...even after changing..oxygen sensor, MAF sensor, coil pack, fuel filter, air filter, good plug wires, crank position sensor, fuel pump, sending unit....if idling low will stall sometimes. Mechanic said it's slow getting spark up just when starting it..not sure why..

My '93 Honda Accord has developed a problem with starting and holding its idle. After the car has sat overnight or for several hours, it may be hard to start. (Sometimes it starts right away!)
It can take several minutes to start idling well or it may be fine in seconds. It's all very inconsistent.

I have been having with my ford ranger. I bought this off my nephew bcuz he needed some money and never drove it due to it being a 5speed and he has a kid and a wife and no room. OK the issue I am having is in gear or neutral I can't get the 2.5 motor over 3000rpms in any gear at all. If you rev the engine up or r driving it when it hits between 2900-3000 rpms the motor acts as if it is going to die and looses all power until you let off the gas. I have replaced the following items on the truck. Oh by the way I have a Cam 2 hand held and there are no codes or warning lights. All new parts :
1) new fuel pump
2) fuel filter
3)new timing belt
4)new motor craft platinum plugs
5) new motor craft plug wires
6)new Mass air flow meter
7) clutch,pressure plate & throw out bearing along with new slave(that needed it replaced others since I was there)
8) exhaust tube behind motor(rotted out)
9) new idle control sensor (acts as elect. Choke)
Truck starts up real quick and idles fine, but when truck is cold the rpms @ 2500 does the same as when it is warm @ 3000 rpms. I even took it to the local ford dealer in my town. Youngstown oh @ Fred martin ford. They told me the wires should be replaced and plugs along with mass air flow valve. I called them after replacing it and told them no difference and the service manager told me to bring it in again and they will look again. Service manager told me he has never heard of this type of problem and I went to a local garage mentioned it to the lead mechanic. He said that is why he doesn't like fords they are to common in chronic problems and can't be fix without a lot of guess work. I have a Hanes manual and did everything it recommends to no avail.

I own a Ford Ranger 2003, 5spd 6 cyl. My problem is when I'm driving and the engine is revving above 3000 rom's. It begins to sputter and buck as if the engine is running out of gas. It only lasts a few seconds. It ends as quickly as it starts. It does not occur each time when driving above 3000 rpms. My mechanic took the truck for a test ride and of course he could not find anything wrong. His advise was to wait until it got worse. I would rather solve the problem now. It is difficult and dangerous when trying to pass vehicles on the road.

Had it before, code p1401. Changed out dpfe and it worked for 6 months. Now spark knock again. Now though I have no codes though. No vacuum leaks that I can find. New egr from before I had the problem. I applied vacuum to the green hose and it stumbled so the ports should be ok. Snytime I go above 3000 rpm i get the pinging. I replaced the dpfe again and no difference.

I have a ford f150 supercab XLT with the 4.6L triton. It starts and idles absolutely fine but when i push the gas to fast(when in park) it bogs down. I just changed the fuel filter aslo...No change.
If I floor it it Bogs then goes up to about 3000rpm (about halfway) and has trouble moving over that RPM or halfway. like theres a restriction of some sort.
If I gradually push the gas, it will go up in rpms and i can get it to about 2000 rpms then I can tack the rpm gauge out if I wanted. but never do.
Also when driving, it seems as if its lacking power..and just to add it does all this stuff while in gear also..
When running It smells of an exhaust leak. but I cant find one. And I cant smell it in the cab.
So there it is. If I think of anything else, or do anything. I will keep posting.

Driving a 2008 Ranger XLT 3.0. Starts runs and drives fine, how ever it seems to have a tinny ruff idle.
What I noticed is when in park or neutral when I idle it up @ 3000 RPMs it seems like it runs on 3 cylinders and sort of cuts in and out very quickly. Is this a protection thing on the ranger.
Running on the road it kicks down and runs thru all the gears normally from idle all the way up to 5000 RPMs. Just would like to make sure this is normal.

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. ??

So that's what if feels like, in park at idle it sounds great, starts great no codes. IF you floor it it will not go over 3000 rpms in park, it feels like it has hit a rev limiter. I have 60psi fuel pressure at idle and at 3000 rpm.
When driving down the road I won't go over 55 mph and drives normal if you keep it under 3000 rpm, if you give it more gas it falls on its face?
AC is not working (clutch not engaging)I don't know if that's related or not.
We did just swap the motor the truck is a 2003 2wd drive. motor came out of an 2002 4wd. we are running the 2wd harness, computer egr delete etc.

I have a 2001 Ford Escape. When started cold, it revs up to abt 3000 rpm. Slowly drops back to about 1000 in abt 10 secs. When the engine is hot, it often wants to idle 2500+ rpms and I have to really step on the brakes to slow the vehicle. When I disconnect the IAC the engine dies. When it is revving high, I can disconnect and reconnect the IAC quickly, and the idle will drop back down for a few minutes, until I step on the accelerator, then start climbing again. It seems to be a lot worse when hot.
I replaced the IAC and TPS about 20k miles ago and thought it was fixed, but the problem has returned. At that time, I could tap on the IAC and it would "get well" for a while. Tapping on this one doesn't seem to change anything. No CEL, engine runs smooth, and I don't notice any air leaks (none that I've found, at least).

I have a 2002 Ford F-150 with a 5.4 Triton. 212,xxx miles. I replaced the cops and the plugs about 6 months ago. I was pulling a trailer up hill last week and the engine was under a load doing about 3000rpm. It began to misfire and give me a flashing mil. However, before I went very far the engine began to run fine. It happened 3-4 different times. However, there is no code recorded. I've driven the truck nearly 100 miles with no problems, but I'm going to be pulling that trailer uphill again next week.

I have a 2002 SuperCrew 4x4 that makes a squealing sound that starts at 3000 rpm and slowly goes away as it approaches 4000 rpm. It does this when you are in park or in gear. I believe the torque converter is going bad, but just want to make sure before I tear it all down.

When I start my 2003 Escape 3.0, the rpm's shoot up to about 3000rpms. After a few seconds they drop to about 2000 and slowly creep back up to 3000. When I put in gear, I don't even have to step on the gas and my vehicle goes. It maintains between 1500-2000rpms as I'm driving. When I come to a red light or stop sign, it lurches like it wants to go even though I have my foot on the brakes. I've replaced the IAC valve, TPS, had it checked for vacuum leaks, PCV valve replaced. I'm at a loss as to what it could be.

2006 Explorer with a perplexing issue that I am scratching my head over. When engine revs to around 3000 RPM, there is a click that sounds like it is under the dash, and the ABS, traction control, and airbag lights come on; if the headlights are on, the dash lights around the a/c controls go out, and sometimes (but not every time) the speedometer and odometer drop to zero. Also, the overhead lighting, if on, goes out. The engine does not appear to be affected. After about 1 second, another click, and everything returns to normal. This happens either while driving or if in park and revving engine. Is this possibly a relay tripping? And if so, why is it triggered by 3000 RPMs?

Experiencing a squeal under hard acceleration at 3000 rpm with roughly 20lbs of boost, not present before and not present after 3000 rpm. light acceleration to 3000 rpm does not create sound, as well as turning 20lbs at a lower rpm (higher gear with throttle input). Truck has an EGR delete, EGR delete up pipe. EGR valve is still in place and plugged in. Truck did come with a banks six gun, so does not have EGR delete tune, however no trouble codes are present. What to check?
