A dirty IAC can cause all kinds of problems with idle. I have seen a thread somewhere regarding the cleaning of the IAC, but I can't remember where.
I am not sure about the 4afe, but the 5sfe has coolant lines running to it, so if you remove it for cleaning, perhaps drain the coolant a little, and plug those hoses until you are done.
