i have a 2007.5 dodge ram 6.7 that i recently replaced injection pump as their was metal in the fuel filter as the truck was spluttering and poping and idleing rough also hesitating when steeping on throttle which the new pump fixed kinda the engine still somtimes on and off will shake bad idleing and be fine other times i try clear the codes but they dont go away so they must be active these codes showed up at the same time. i was hoping after replacing the injection pump it would and it is better but is on and off acting weird anybody now what may be wrong thanks

I'm assuming you did not replace the injectors? If metal made it into the pump, more than likely it made it into the injectors and possibly damage one or more. I would look towards the injectors and maybe do an injector kill test to figure out if it is in fact the injectors.

Welcome to CF
Be thankful that bully dog didn't brick the ECM as they have done to many 3rd Gen trucks.
