Where is the idle control valve on the 1999 Cadillac De Ville and is it the same thing as the idler motor?


The IAC or idle air control valve is mounted in the throttle body and uses an air passage that opens or closes to increase idle speed where as an idle motor usually pushes against the throttle plate to increase idle speed most idle motors (stepper motors) where phased out and was never used on port fuel injected engines chances are you have an IAC valve

I have a 93 cadillac seville sts,the car will start but let off the gas and it dies, it wont idle, the pedal will even move on its own sometimes, oreilys said the idle air controll, is this right?


The person who gave you this advice are they a trained auto repair tech?? no. Have the dealer test the idle speed control system and see what shows up. DO IT RIGHT AND DON'T LISTEN TO THE MINIMUM WAGE SCREEN READERS AT OREILEY.

How do i remove and clean the IAC


Operation

The Idle Air Control (IAC) valve adjusts the engine idle speed. The valve is located on the side of the throttle body. The valve is controlled by a duty cycle signal from the PCM and allows air to bypass the throttle plate in order to maintain the proper idle speed. Do NOT attempt to clean the IAC valve. Carburetor tune-up cleaners or any type of solvent cleaners will damage the internal components of the valve.

Removal & Installation

  1. Disconnect the negative battery cable.
  2. Detach the IAC solenoid connector.
  3. Remove the two retaining bolts and remove the IAC solenoid and gasket from the throttle body.
  4. Installation is the reverse of the removal procedure. Use a new gasket and tighten the retaining bolts to 71-97 inch lbs. (8-11 Nm).

2001 Cadillac Sts: engine will die while idoling and sometimes while im driving...it also bogs down when driving and the service engine light will appear and b4 i can get it checked the light goes...


First item that I would check is the idle control valve. you can increase the idle speed of your engine if it runs below normal. Since you get a check engine light, I would suggest to get the error code.

Here is the most common cause of this stall, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) 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
