1997 GTP Supercharge Issue....

Here's the funny part about the IAC and vacuum leaks. When the IAC is working properly it will nearly close to combat vacuum leak issues. Therefore it's more likely to be an IAC screwing up than only a vacuum leak. Don't underestimate that you likely have vacuum leaks though.

Merely suggesting the first place to look.

Got it figured out today...Turns out it was the Air Control Module....I brought it to the shop this mornin and a guy leavin said he had the same problem and told me to talk to the mechanic, well I talked to him, got it fixed and now it doesn't do it....Not a bad buy for just running into a $70 part/labor right away.
