When I down shift from any of my high side gears more so when loaded at 30-44,000 lbs I get a miss fire or chugging from my motor. I lose all power climbing hills of all sizes (don’t feel it as bad on flat land) and once I’m back into 13th gear and feather the accelerator, I can feel the miss fire feeling go away.
The only code is for #5 injector and i already replaced it and still having the same issue. My check engine light is off.
PLEASE HELP!!!
