My car is idling too fast, where is the idle cable,so i can alter its idle speed , i have a 1995 bmw 316i se

IDLE AIR CONTROL MOTOR IS INOPERATVE AND HUNTING FOR IDLE EQUILIBRIUM

Does the engine slow down in drive, or is it still running fast and trying to pull away from a stop ?
The problem could be a vac leak, or a sticking idle control valve.
The computer controls idle speed by how much air enters thru the control valve.

Check for idle speed sensor fault code and crank position sensor

itis mounted on the throttle body, as it is in all vehicles.

should be on top,easy to get to, at your intake mainafold. follow cable fron firewall to the intake. then you should see a nut on end of cable, nut is the adjusment.

belt is bad.

Hi.

Check accelerator cable, idle air control system and idle speed control motor(ISC), air intake setting and sensors, check the vacuum system. Scan the PCM for diagnostic trouble codes. ISC, vacuum leaks and air intake problems are the most common cause for fast idle on this car.

Fast idle could be the result of a few things; however, I would start with your Idle Air Control (IAC) Value. This is is mounted on your car's throttle body and it controls your vevicles idle speed under various conditions. It is easy to access. Try cleaning your IAC. Even a little bit of carbon build up could impact your car's idle.

Your car doesn't have a choke. Fuel injected engines alter the mixture using information from the sensors to give the right mixture all the time, thus negating the need for a choke. This is only for carbureted engines, and your car is not. If it's idling fast, you can change the settings on your idle set screw, or have it tuned.

Sounds like a vacuum leak, check and listen under the hood at each vacuum connection and hose.
