this was a real life saver. I don't mind paying the money to have my car fixed but 2 mechanics could not fix my idle problem. I even pointed this thread out to one of them and still no results. I have 0 experience fixing cars but I followed these steps very carefully and my car is running as if it were new! I performed the IAC cleaning about 2 weeks ago and not even a hint of the problem still exists. What a relief! Thanks for posting this.
