Answer
Hi Bobby,

Never made sense to me why someone would just start replacing parts without testing them to see if the parts are actually bad. Never rely on your computer to tell you what is bad, it only tells you what problems it is experiencing and a good technician should be able to gather from that information what to test and that will determine what to replace.

Sounds like your IAC valve may be partially blocked or you have a vacuum leak. Have a reputable technician in your area look at it to be sure.

Looking for a reputable service technician? My advice on finding a good technician is: Steer clear of the dealership and 'chain' stores like Firestone, Sears, Pep Boys, Monro Muffler/Brake, Midas, etc. as they usually only employ ONE ASE Certified Tech just so they can say they do and chances are, that guy is the asst. manager or manager and is not in the store to diagnose/repair vehicles anyway. Find a service location in the link below or get some names out of the yellow-pages and do a drive-by. Garages that employ ASE Certified Technicians will be marked with the 'Blue-Seal' insignia. If unsure about whether a place employs Certified Techs, just ask to see their credentials. ALL ASE Certified Technicians will be PROUD to show and display their certificate(s).

Thanks for the question, I hope this information was helpful to you.
