waterdawg Posted June 22, 2012 Share Posted June 22, 2012 (edited) Any Codes? Could be a bad cam, #7 injector, or maybe injector cups. Have you had those updated yet?Not a mechanic myself. I am just giving you ideas based on my experience with granite's. Edited June 22, 2012 by waterdawg Quote Link to comment Share on other sites More sharing options...

Dzlbudman Posted July 19, 2012 Share Posted July 19, 2012 Did u mess with the cruise control lately? If yes go to the dealer, you can hit the cruise buttons to many times and it brings the trucks idle down to 650.. Quote Link to comment Share on other sites More sharing options...
