    My car idles at about 2.5 rpms until I put it in gear and drive. When I come to a stop, it idles high again. It doesn't do it all the time but 98% of the time. Check engine light is on as well.

Have you tried to run the car with the intake off. if it still idles high than it is an internal air flow problem and something could be blocking it such as a temperature sensor or the throttle body isnt opening correctly.

Can be a number of things (check all of these):

  1. Stuck throttle linkage or accelerator pedal;
  2. Loose butterfly on throttle body;
  3. Stuck or malfunctioning idle air controller;
  4. Loose or damaged throttle body or bad throttle body gasket;
  5. Cracked intake manifold or bad intake manifold gasket;
  6. Bad ignition control module.

High idle after replacing idle air control valve


There should be a rubber o-ring around the base of the section of the iacv (the portion that fits inside the manifold). Make sure this is seated properly. If it is not you may be allowing air to pass. This would increase idle speed. Also make sure to check that the valve itself is properly seated and tightened into place. If no this may also allow air to pass unrestricted into the engine. Good Luck

In my 2000 Saturn SL1 I am experiencing very high idle (2000 rpm warm - higher cold). I have cleaned the throttle body and the idle air control valve with no improvement. What next, replace the idle air...


You could try replacing the idle air control valve but I would obtain one from a local salvage yard, its cheaper and you are not certain if thats the problem, another thing i would check is your intake manifold gasket where it meets the cylinder head, if tha gasket is cracked or leaking it will allow excess air to enter the engine and make it idle higher, the easiest way to verify this is get a can of carb and choke cleaner and spray it all around the intake gasket area, if the engines idling characteristics change drastically then the gasket is bad and needs to be replaced if theres no change in the idle I would start looking for vacumm leaks and the idle control valve issue, which you specified.

When I come to a stop, the car dies. After idling for a few moments, the RPMs start dropping below 1000 and the car dies sometimes. What's my problem? I just replaced a fuel filter, and it was running...


Here are the common cause of surges, cold stalls, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Idles high


Zab, First things first, check for any vacuum leaks, hoses that are disconnected, cracked or just plain worn out. Also check for vacuum leaks around the throttle body.
It really sounds like you have an EGR valve that is stuck open ever so slightly. The MAP sensor is a result of a low manifold vacuum. The IAC (idle air control) motor is trying to compesate and keep the engine running resulting in the high idle speed. I would remove the EGR valve and clean it gently with a brush and pick to remove any carbon build up.
Let me know, regards.
