I have a 2023 Ram Rebel 1500 w/ 5.7 Hemi ETorque with ~51.4k miles. Minimal trailer towing, a good bit of long highway trips, limited idle, commute ~65 mi per day for work. I have the larger fuel tank and rarely put more than 28 gallons in it. Last week put 31 gallons of 87. Next day started running rough, engine light went on and was flashing making audible tone, and popped P0300 code on my reader. I parked it and had it towed to the dealership. They stated their code reader is a cylinder 6 misfire. Dealership stated the plugs are bad and need replacement and then they will further troubleshoot if it remains an issue. Anyone else experiencing similar issues with stock plugs/bad misfires at 51k? What should I be asking / thinking about. Any assistance would be most appreciated. Ryan
