Hello all. I have a m35a3 with the 3116 cat. The truck runs and idles great in neutral. You can rev it and its fine as soon as you put it in gear and put a load on it it starts to break up and the fall on its face. Pull over put it in neutral let it idle then it's fine in neutral put it in gear and put a load on it same crap.... I've cleaned the check valve in the tank changed the fuel filters and still same thing I'm lost. Could the pump be taking a sh&t or the seals on the injectors I don't know.. Just not sure on how you can rev it fine in neutral but the put it under a load (put it in gear) it falls on its face?? Any help would be great thanks
