1990 300zx n/ai cant get my idle below 1000 rpms even when the idle screw is all the way in! i just got a new bigger k&n, removed and cleaned out the idle air adjusting unit with wd-40, i checked for vaccum leaks the best i could, and i'm still stumped. no fault codes on ecu. if anyone has any suggestions it would be apprieciated.
