Ok...newbie question. I've been reading around in here for a while I keep seeing IAF listed in a bunch of posts, mainly as a potenial problem with idling. What is a IAF? Sorry, but I did do a search but everything is listed IAF, not spelled out anywhere.
Thanks
The IAC gets clogged with carbon after a while and must be cleaned with throttle body cleaner. If you don't you eventually with start having trouble starting your car in the morning.(It'll crank and not idle)
