OK.... so it was just once or twice in the mornings but now its all the time....

When I stop, my engine revs up to anywhere between 2-3 grand when normally its at 500 rpms. This is ONLY when I stop and the box seems to go back to normal when Im driving. Ive not got any real mods to the engine besides a CIA and pulling off the power I have a 25 amp compressor for the bags. I had never had a problem with it all before until about 2 weeks ago. What could it be? Idle Air, throttle sticking, vaccuum leak? Anyone else have this problem. Im at 85,000 miles and since the bags dont really drive the box hard. Help! I just need to know where to start.
