Driving home from a 80 or so mile drive the truck started to misfire at about 70mph with cruise control on. So i slowed down to 50ish and floored it to 85 and the problem didn't come back till I got like 5 minutes from home. And same thing. So I floored it again from like 30 and went to 95 or so and got home fine. I threw the code reader in when I got home and it read those 2 codes p1128 and p1129. No loss of power when floored through so that kind of rules out the fuel pump. Im guessing maybe an injector clogged but it was a dangerous issue that I dont want to happen again. Any help or other ideas would be greatly appreciated.
