2003 GMC Yukon XL 2500 SLE 8.1L MIL Lamp on
Posted to GM Driveability on 9/20/2010 10 Replies

Hi all, This keeps setting a code for a large e-vap leak. The gas cap has been tested. The system has been smoke tested. It has 2 gas [...] wondering what to do next. Thank You for any and all help, Greg S.
