Hello,
I have a 2016 6.7L Cummins with around 108,000 miles.
The truck has been great with hardly any issues.
I did have the heater core replaced, and now the truck has been acting weird sometimes, and sometimes it acts fine.
The symptoms are rough idling, surging /unsteady when accelerating, and there has been a knocking noise sometimes when I stop or let off the pedal.
When I am riding slow or stopped, the truck will sometimes jump forward but not always.
The truck seems to begin acting differently when it has been running for 20+ miles.
The check engine light will come on, and the service electronic throttle control will come on sometimes, and then they will go away until they reappear.
I went by Advance Auto Parts and had them tell me the codes.
The codes are as follows:
P0473
U010E
P0336
P0721
P0736
P0933
P2703
The truck is tuned with EFI Live while deleted; this all happened around 75,000 miles ago.
Does anyone have any input on what may be the issue(s)?
I really appreciate any help you can provide.
