The other day I was driving down the highway and had to punch it, it accelerated fine until around 60 to 65. Then it sounded like it misfired and I got the engine trouble code, also lost all power had to pull off then turned off the truck and restarted it and worked fine. Few days later same thing happened again? I just put 315/70/17 tires on too. Any help at all or advice would be greatly appreciated!
