BLKSMK and I were truckin' around and rolling some coal. When my brother-in-law BLKSMK tried to pass me I nailed the throttle and heard a pop which forced me to give him way. After that, my truck is now missing in all tunes including stock. I replaced my fuel filter, took it for a test drive and everything seemed fine. Shortly after, the problem re-occured. There is no SES light. When the truck misses the RPM fluctuates alot especially in high tunes. Does anybody now what is happening? I need help cause I'm bombed out. Any advice will be greatly appreciated. WTH!
