New truck back at dealers. I have owned it a week and a half and most of that was in the shop for the shift out of park issue. This time it is a flashing engine service light that happened at 100km/hr. I am not sure how long, as when I noticed it, it stopped. Checked the code when I got home and it was p0300. Dropped it off at the dealers and they ran it, checked it, called it in, cleared it and shrugged their shoulders. cylinders 3 and 8 showed a history of misfires. Suspect a faulty dynamic fuel system, but not sure until that throws a code.
hopefully is was a random once only, but I am losing my confidence to be driving anywhere remote.
