  1. No and probably won’t  attempt it . I am trying  to get a feel for what or how to diagnose the problem . I just hate taking it In with no clue ? Im sure it involves the two front cylinders , thinking it may be odd for 2 injectors to croak at the same time . Just don’t want to start experimenting without some knowledgeable advice . I know these engines are computer controlled , wasn’t sure about loosening injector lines or other manual testing methods  ! Thinking I will lift valve cover on front and take a look for loose rockers on the two cylinders that are in the 150 degree range. What’s your thoughts ?

  2. Sounded like engine skipping through exhaust (appeared to be a dead cylinder).  Felt loss of power and as I throttled truck, sounded like spark knock (lightening bolt appeared on dash but before I could count blinks, it cleared).  What would I be looking for or checking into that may cause this? Sounds to me like an injector trying to work, but not working.  Does not sound like valve train - sounds like an individual tick.

    Any leads on what to check on next?  

  3. At a loss on this issue ? I have a 2007 Mack Granite CV713 dump with no low air light or alarm working . When I lock axle on dash switch , an alarm sounds in dash (was told it was the same alarm (buzzer) that should sound off for brake .?  Also through all the reading about this issue some people are talking  about the dash being bad ? Any thoughts ? I do have access to a 2004 model truck that I could possibly change out  the dashes if they interchange ? any thoughts or ideas
