Hey guys, so I have been having problems with the engine revs not dropping like they should in between gears. During regular driving, say if I shift at 2500 rpm and I push the clutch in to get ready for the next gear the engine speed remains the same until I let go of the clutch in a higher gear but only with the a/c on. So I was advised by a few fellow members here that I should clean the IAC valve. My question is what should I use to clean it out? I've never taken out the IAC valve before so I don't know what to expect. Should I just wipe it off or should I use break cleaner or something? Thanks in advance.
