The fix is
With the engine off, remove the air line running into the throttle-body (the silver thing on top with the hose running into it), clean the throttle-body (metal flapper door) with air intake cleaner (its about $3.00 at most auto stores). Open the throttle, and spray the air intake cleaner into the small square hole in the bottom of the throttle-body (this is the IAC control which is causing the problem).
