Trying to figure out what is going on with the work truck. I’ve got a 2007 1500 Laramie 4x4 with the Hemi. When accelerating lightly the truck feels like it is bogging down and almost feels as if it is shuddering. If I press down harder on the gas it will down shift and then accelerate like normal (most of the time). On occasion the CEL will come on when it first down shifts, dings a couple times, and then goes back off. I can’t ever get it to keep the code to figure it out and correct it.

need a tune up?
need a tuner?
need a new 2500 Cummins?

 

If the CEL is flashing that says misfire…..probably have a coil going out or plugs
