ASE MASTER MECHANIC TEXAS 1/16/2011The EGR has not =-a to do with truck turning off..... Does it keep running like going down the road, or is it just trying
to die, and just keeps popping and chugging?????
If it won't turn off at all, that is in your ignition switch where the key goes in , about the only way to kill it is to remove
the neg, battery cable very carefully.
Bill 1/17/2011Sounds like a carbon build-up in cylinders or a timing problem.
