On my maiden voyage after picking up my travel trailer, about an hour into the drive I got a misfire in cylinder 6. I drove it the rest of the 45mins home. Swapped plugs and coil packs with other cylinders and the misfire remains in cylinder 6. It shakes the truck pretty violently at idle. I’m not sure what else to do from here. Wondering if a fuel injector is stuck open due to smelling like straight fuel when i idle it. Was goose tuned but switched to the cob performance tow tune.
