Ever since I had my fuel gel up on me a few months ago when we had a negative teen cold snap, I’ve noticed that when I put a big load on my truck at lower RPMS (slowly rolling into the throttle when towing something up a decent hill but the transmission stays in overdrive)…I will get what feels like a misfire from an injector. Just a little stumble that I can feel, almost like a cylinder isn’t firing (no fuel) for a split second. I’m not getting any codes that would indicated a bad injector. And the truck runs fantastic…except for that issue when there is a big load on it at lower rpms. If it downshifts and the RPMS’ go up, no issues at all…it makes great power, and no misfire feeling.

I did get several “injector contribution” faults when I had my fuel gel up…..could that have damaged an injector(s)? My next step is to take it to a shop and have them run a test on the motor and see which injectors may be weak.

Does that sound like an injector issue? Or something else? Is it a common issue in the 6.0’s to have injector issues after the fuel gels up in them?

Nobody has any ideas? I've got Forscan and tried to see if there was an Injector Contribution test I could run to see if there were some bad/weak injectors....but it doesn't look like it has that option for the 6.0 PSD's.
