IAC = IAB = the thing cylinder attached to the throttle body
as far as the protective coating, i always use GUMOUT TB cleaner, works great on TB and IAC. some people say not to harm the protective coating since spray cleaners may/will remove these coatings. u know what, if the TB is gummed up the coating is obviously not working! use a rag soaked in cleaner and clean the crap out of it, then run the car and spray some more in there to get the hard to reach areas, especially where the where the moving parts are.
i would also clean the MAF with some electrical contact cleaner, some use TB cleaner as well, but i have only used elec contact cleaner.all in all, I am fairly sure your TPS is your problem.
