Just installed my CAI, and decided to clean the throttle body while I was in there. Pulled the IAC to clean it. Used brake cleaner with a toothbrush. There was some corrosion on the tip that would not come off. I don't think a Scotch Brite would have been any more effective. Would emery cloth hurt it, or should I just think about replacing it? BTW, noticed that the belly pan gasket is leaking, so I'll be getting into it again soon.
