2004 Chevrolet Silverado 2500 HD 6.6L MIL Lamp on
Posted to GM Driveability on 11/13/2009 3 Replies

this thing smokes bad, black and blue smoke (blue like oil) has EGR performance codes P0404 open position performance and code p1404 closed position performance. Going to start trouble tree but if anyone could point in the right direction let me know, thanks.
