Anyone get the "check gas cap" warning? Last week it popped up on the display on my 2004 Grand Prix. I tightened the cap a few times but it keeps coming back. Anything else obvious I should check?
Thanks.

Try a new gas cap. If that's the problem it should clear after a few starts. A round rubber seal wears out from twisting closed/open.
