ImUrOBGYN Posted September 8, 2008 Report Share Posted September 8, 2008 check the idle air control motor And if that don't work, be sure you're throttle body is closing properly. If it is, check your tp (throttle position sensor). If it is your tps, be sure to reset your timing after adjusting/replacing it. Quote Link to comment Share on other sites More sharing options...
