Hey guys just need a little advice I know some one else on here has probably had the same problems as I am having. Cummins Engine Company specifically points out in their trouble shooting manual for the following complaints

Engine Difficult to Start or Will Not Start (Exhaust Smoke)
Engine Power Output Low
Engine Runs Rough at Idle
Engine Runs Rough or Misfires
Smoke, Black - Excessive
Engine Shuts Off or Dies Unexpectedly or Dies During Deceleration
Engine Will Not Reach Rated Speed (RPM)

These are some of the things that I have been experiencing on a daily basis want to take it in cause its under warrenty still only got 33,000 on her but I am worried about the bully dog chip, no cat, an intake. What do you guys think anyone had the same problems any addvice greatly appreciated. Thanks

 

sounds like a bad injector or two when was the last tiem you changed the fuel filter and ran a fuel treatment? bullydog maybe a problem if the dealer looks for it but remember most people( me included) believe you play you pay.

 

Changed fuel filter about 3000 miles ago havent ran any fuel add. what you think should i run some in it? what kind would you guys recommend
