glenn2726 Posted December 28, 2006 Share Posted December 28, 2006 Hi, check my reply to Applejacks idle problem, sounds like yours is the same, it's the Idle Air Control Valve located on the front of your engine, it controls the amount of vacuum your engine needs to run smoothly....

jzz30 Posted December 30, 2006 Share Posted December 30, 2006 its on the radiator towards the bottom where the drain valve is. the resistance should read 1.48-1.58 ohms at 80 degrees C Quote Link to comment Share on other sites More sharing options...
