Have you done any work to the car recently? Sounds like you have a vacuum leak.

If you havent done anything recently that would cause the leak it maybe time for a new IAC or a good cleaning of the MAF.

Try to reset the idle. Search for "idle reset" and follow the procedure exactly how its laid out.
