Have you had the oil tested? That will tell you if an injector is leaking.
Do you run Mopar/FleetGuard/Racor fuel filters?
I have not. How is that done?
I’m not sure what the fuel filters are...maybe old/bad/generic fuel filters are the problem?
Racor, Fleetguard and Mopar are most likely the only filter for the rear filter.

I would check the harness/valve cover gasket first. It all comes as one unit. I have seen screws come loose and chafed wires that cause similar issues.

How many miles? Lots of people have 150-200K miles on stock injectors with the 6.7. Its possible to have 1 bad one, but 2? Unless you are up there in miles, I would suspect the injectors are fine or you just have bad luck. The fact that something happened to cause #4 injector to throw a code, but it didn't come back makes me think its not the injector, but something else.
I would start by making sure all your wiring harnesses are in good shape and securely fastened. I'm guessing that something is loose in the injector wiring harness that is causing a voltage drop somewhere that is causing the code. The wiring harness is the first place I would look.
At a bare minimum I would say you need further diagnosis. Good luck!
