It's a 2000 buick century with the 3.1. Idles at ~3500 rpm in park. I haven't looked at it yet, but suspect it's the Lower intake manifold gaskets.
Does anyone have experience with these? Any other common areas to check?
It's my buddies wife's car, and I've already recommended the gasoline and lighter trick (he agrees, the wife just wants it fixed). The car is an utter toilet with just over 100k miles on it. They are just looking to get a few more months out of it before trading it in.
EDIT: The car was tuned up less than 10k miles ago, and the IAC was replaced ~2 years ago
