ollyb 0 Posted August 30, 2004 1.8 engine and idle seams to be low, also hunts alot between 700 and 2000rpm on idle. Other than the idle control valve on top of the head what else can cause this? Quote Share this post Link to post Share on other sites
aide 0 Posted August 30, 2004 Your basic idle settings might need resetting. Or could mixture - should be 2%, if your having problems starting then probably that. Quote Share this post Link to post Share on other sites
ollyb 0 Posted August 30, 2004 No starts fine runs fine have to find a new idle control valve as it just hunts about on idle. Quote Share this post Link to post Share on other sites

potatonet 0 Posted August 30, 2004 Check to see that you have the knock sensor/ idle stabilizer valve plug on the back of the throttle body plugged in, I had the same problem till I plugged that in, then I realized that the boost build rate sucks and then unplugged it again so that my car wouldnt be so slow off the line.
