Cleaned the throttle body yesterday. Followed Remerson228's post. I tried to clean the IAC, but it had quite a bit of corrosion on it. Used a toothbrush and brake cleaner, but I couldn't get it clean. Didn't look like Scotch Brite would get it either. Would some light emery cloth be OK to use, or is replacement a better option? Need to get back in it again because the manifold gasket is leaking. Attached some pics of the IAC.
