Hi scotty i have a high idle like 3000 rpm in park in drive or any other gears its around 1000- 1500 rpm i changed mass airflow sensor air filter idle air control valve also changed fuel filter prior to all this and throttle position sensor any idea what it may be? I have to clean throttle body still but the idle bounces up and down so i dont think its just a dirty throttle body im thinking maybe a vaccum leak? Any suggestions would help greatly i do most of my own repairs from watchin your videos but this is the only thing so far i cant figure out please help scotty car has just under 180,000 i checked plugs and coil packs also and they were good {black}:idontknow:
Actually dirty throttles often do that because the computer tries to compensate clean the throttle first if not that do my video finding engine vacuum leak Scotty
