Change the pcv valve and check/change the mapp sensor, you may also want to take a look at the egr. All possible culprits.

I'll bet your IAC is either stuck or has quit[idle air control motor]. Have you or your tech checked that? Sometimes it can be removed and cleaned with success.

That too. You may also want to clean the throttle plate too, if its carboned up, then it can stick open or closed
