the IACV on the other hand, ive tried cleaning it and its never worked for me. i cant remember exactly, but i dont remember it being exactly cheap. i think it was about 110 dollars or so...
I was atempting to clean the IACV assembly myself, but gave up because its to tight to get at with my hands.
Question for you Asleep, when you said "its never worked for me" are you saying that cleaning it didn't solve the idling issue I assume you had or have?
