Turtlehead Posted April 30, 2010 Share Posted April 30, 2010 Could be many things. Can you provide anymore information or what you have looked at/replaced? Quote Link to comment Share on other sites More sharing options...
preludechic Posted April 30, 2010 Share Posted April 30, 2010 i had simliar problems but knowing what you have replaced and what not would be a great way to point you in the right direction ! Quote Link to comment Share on other sites More sharing options...
H22J03Y Posted June 9, 2010 Share Posted June 9, 2010 make sure your coolant is full... if its empty it will cause the car to idle up and down. could be your iac sensor as well. try those and see if it fixes it. Quote Link to comment Share on other sites More sharing options...
Repsol Posted October 9, 2010 Share Posted October 9, 2010 My idle problem was the FIT Valve. Popped the cover off, and it had completely backed all the way out, just screwed it back in all the way, idle surge was fixed. Quote Link to comment Share on other sites More sharing options...
