sonyman87 Posted March 28, 2004 Report Share Posted March 28, 2004 check for an air leak after your map sensor Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted March 28, 2004 Report Share Posted March 28, 2004 Yeah.....a bad alternator will not make the rpm surge. Your first problem is most likely a bad IAC motor. The second problem could be the EGR....or something in the ignition, like a coil Quote Link to comment Share on other sites More sharing options...
whoyourdaddy49 Posted March 28, 2004 Author Report Share Posted March 28, 2004 the reason for taking th intake was cause i had a coolant leak Quote Link to comment Share on other sites More sharing options...
Slade901 Posted March 28, 2004 Report Share Posted March 28, 2004 Just like they said probably the IAC. I would also bet on failed TPS. Quote Link to comment Share on other sites More sharing options...
