Alright, So I figured id give forums a shot for some assistance. I have a 01' 2500 5.9 24v Cummins w/ a 6spd manual and it died on me going down the highway. I tried turning it over and after a bit it started and had a terrible loping idle and a dead accelerator pedal. However, I can put it in first and let off the clutch and as I let off of the clutch the truck picks up the rpm and runs perfectly fine for the duration of me letting of the clutch. Am currently suspecting APPS. Anyone have any ideas?
