I would say its your Idle air control valve. Clean your air filter too.

SOURCE: Cold days 94 f-150 high rpm start

probably is a emissions sensor problem, lots of these parts are plastic. check out the throttle cables, lub em wd40. there is a type of valve somewhere on top of engine, it may be cracked, pcv valve stuck. lots of possibilities, almost too much for solution online. something emmissions with an electronic sensor is acting up.

SOURCE: transmission shifts after i reach 3000-4000rpms and let off the gas

A transmission service may solve this,check the trans fluid it should be ruby red and clear anything else and it needs to be changed along with the trans filter.

SOURCE: 1996 explorer stalling

Sounds like a bad I.A.C. (idle air control) motor, or I.A.C. switch located on the side of the throttle body (dr. side) if i remember correctly. I ran into this on a '97 sport i used to own, if you go to remove it the screws (phillips head) are usually in there pretty tight. Keep me posted on if it helps.

1999 acura tl 3.2 at 3000 rpms it acts like it has a rev limiter. An it wont let it shift until you let off the gas


Hello
The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM

Ford Focus ZX3 2.3 eng reving over 3000 in neutral


Could be a vacuum or intake leak somewhere.
Could be sticky IACV (idle valve) these just bolt onto the intake manifold with a couple of wire plugged into them. Give a spray with carb cleaner to get gunge out then spray some thin oil onto the moving parts. Hope this helps

My 1992 ford exploer will not hold a steady idle. I replaced the throutle positioning sensor.when i start it, it revs to 2 rpms then cuts of and sometimes it runs but the rpms go up and down for about 1 to...


  1. baring a major vaccumm leak
  2. idle speed control motor is probably sticking
  3. it is a 2 wire soleniod with an air shuttle which allows air to bypass the throttle plate.
  4. when acting up at idle tap the idle valve repeatedly with a small hammer.
  5. does idle change?
  6. if so replace valve
