I think my IAC is on its way out. When my engine is cold and I start my car to let it warm up after a few mins of warming up the rpms start to cycle. it goes from about 1200 to 1700. it drops then goes up and it does it for a few mins then it stops. Then when I am driving when I come up to a stop it does the same thing for a bit too. It goes from 1100 to 1400. I am sure its the IAC because I have seen the same thing before on a different car.
