Leg93 Posted April 1, 2006 Share Posted April 1, 2006 Two questions in one day! I'm on a roll! Sometimes when idling the RPM's will just surge for a second...just enough so that if Imy foot is just resting on the brake the car leaps forward. When it is just warming up it sometimes surges between 500 and 1500 RPM's rythmically for a several seconds. Any ideas? Could this be a vacuum problem?

Skip Posted April 1, 2006 Share Posted April 1, 2006 assuming this is your 93 2.2 EJ22 ? first place to start is a cleaning of your IAC valve (Idle Air Control ) Notorious for getting gummed up and sticking plenty of info on cleaning them, many posts on the problem, should be part of routine maintenance I feel.
