loose fan belt?

Put the car in neutral, set the parking brake, open the hood, get someone to listen/see where the sound is coming from, as you press on the accelerator.

It is the Intake Air Control motor (IAC Motor). Replaced mine and have not had any other problems.

SOURCE: wont hold idle will start with foot depressing gas pedal will run with foot on gas but stalls when foot removed

Check and clean Idle air control valve. Make sure its responding to signal as well. Also make sure ther are no vacuum hoses disconnected. This may not be a "cure" but it's a good place to start.

you have to get scanned for fault codes..possible camshaft sensor if you have starting issues..if car is working fine,could be an evap leak..let me know
