• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Hi Everyone,...I Hope We Can All Share Our Grand Prix EXPERIENCES & Learn Some Relavent FIXES Also..!? I OWN 2 IDENTICAL '08 ( Last Model Made ) - Grand Prix's, 3.8 Liter,6 Cylinder...& Have a "Check Engine" Light on Both of Them That Came on @ ARound 60,000 Plus Miles...Anyone Tell Me ....How to Turn off This Light? I Checked the Codes That Came Up & Replaced The Gas Cap as Was Indicated...But The Light is "Still ON"...PLEASE HELP,...Anyone..???
 


Welcome!

Probably evap.

You should be able to erase codes with your scanner. If you don't have one, you can disconnect your negative (black) battery terminal for like an hour. If the codes return, it's likely you have a dirty evap canister.
