This is a world famous issue but its a simple fix all you have to do is take the IAC off and clean it with brake parts cleaner, carb cleaner ect... Then put it back on if that doesn't fix it (and all your vacum lines are good and no leaks along the 23 feet of intercooler piping) then you need a new valve.sweetride2go wrote:It idles high cause of a sticky IAC. Sometimes it idles lower, sometimes higher... lol
