Question about 1993 Saturn SL2
I replaced the manifold air filter erg valve and cleaned the throtle and replaced the sensors why is it idling so high and the check engine light stays on. Diagnostic says its an air flow issue> So whats next
I had the same problem, much money spent for nothing, it ended up being the temperature sensor on the side of the block, advance auto, had the part for 10 bucks,

Have you tried to run the car with the intake off. if it still idles high than it is an internal air flow problem and something could be blocking it such as a temperature sensor or the throttle body isnt opening correctly.
