2003 Chevrolet Silverado 2500 HD 6.6L Misfire
Posted to GM Driveability on 2/22/2010 4 Replies

Nasa called and they want their shuttle back! I got this Duramax that has what I think is an injector or sleave problem but I cant prove it out because the scanner keeps dropping communication when I try to run a balance test or even just reading codes or fail...
