If you have a idle problem, this fix wasn't found on the internet, straight from GM. Just a chance it may work for you if you have run out of options.

Fix

After a long fight , this fixed mine. It ran awful and the dealer found a bad connector on the MAP sensor. Couldn't tell by looking at it. Replaced plug and wired it into the harness and so far so good. Just something to look at if all else fails. God knows that I tried everything else.
