VERY SNAPPY CM870 - 3406E - 06-15-2024
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.

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