VERY SNAPPY CM870

[3406E]

Just started to test truck out and as you touch the throttle pedal it turns into a bounce about. I gotta start off in 3rd really slow and baby it to get somewhat of a decent take off. But the problem is really. Can it be adjusted, who where to get it done? I have insite but don’t have the calibrations yet. NEED YOUR HELP PLEASE. THANKS

Accel pedal settings set incorrectly?.

- Put the original 100% factory program that belongs to that engine and truck in it and see if it drives more normal.

Thanks, is that only done by Cummins dealer?

Hearing it can also be a problem of the accelerator pedal sensor gone bad. Or the harness for it to the ecm
