Exhaust in cab

[Jeff_R.]

Does anyone have any guesses on why I'm getting exhaust in my cab? The shop tells me they can't find any leaks but 2 injectors are starting to go bad.

Factory exhaust????

[Jeff_R.]

Yes, my engines exhaust. It's so bad I can't drive the truck w/o the recirculate on.

Two things................. Are you still running FACTORY EXHAUST system and what year, make and model truck are you driving? What engine as well? LB7, LLY, LBZ, LMM? :)

Factory exhaust, '02 Chevy 2500HD Duramax, LB7 engine, 115k.
Thanks.

I may be wrong but if IIRC there may be a bulletin that pertains to this complaint.
