The fluctuating idle just started after replacing the MAF, last week. The AOS was replaced in October. Car ran better and of course no smoke but still had CEL. Was told by a Mechanic I know that the k&n air filter could cause MAF issues, replaced the kn with a new Wix paper filter, cleaned the MAF, car ran great. Still had CEL. Cleaned the MAF several times still had CEL. Replaced the MAF and that when the massive fluctuation in idle speed started. Guess I'm going to have to break down and haul it to the dealer in Albuquerque.
