Hi, I'm the noob here today. Long time Pontiac owner, a couple of sunbirds, '00 Bonneville, all since sold, and currently a '2008 Grand Prix and a '69 Firebird Convertible (owned for 25 years).
I found this site while trying to get some info on my 2008. I'm having an issue with the "loose gas cap" and "check engine light". I tried checking the FAQ's section and other forums with no luck. I'm sure someone else here has had issues. I have changed the cap (twice) but the light still stays on. I'm sure that means there is a vacuum leak somewhere in the evac system. Any ideas on where to start the search will be greatly appreciated.
This site looks to be very informative and I'm looking forward to being a contributing member. Now I'm going to try to set my profile.
