did you mess with or remove your PCV lately? lets say you capped it off and left that tube from the valve cover to the TB you would be experiencing a vacuum leak. if thats the case just run a breather on the valve cover.

Test the TPS sensor, That sensor is capable of alot of strange **** when it goes bad..Mine idle'd at 1500 and when driving under very very little load when it shifted it would chirp the tires hahah. Crazy stuff
The best thing to do is monitor your IAC counts with scanning software, aside from visual cues like broken vacuum lines, etc. Do you still have the fresh air supply hose on the passenger side valve cover?
