Idle Problem

Check out the surging idle sticky at the top of the forum page.

Good luck.

the idle air control could be stuck shut, not allowing enough air into the engine, you could try to clean it. or the EGR valve is stuck open and allowing dirty used air into the engine, try cleaning that, it can cause idle problems. if you unplugg the mass air flow sensor, and the idle doesnt change, you might have a bad MAF sensor. my car idles around 500-600 when i unplugg the MAF sensor, and it surges a little, and begins to cut out but it keeps running. these are my thoughts.
