While driving down the road today the truck jolted and the CEL came on. I pulled off and turned around to head home. I went pretty slow and made it home. I tried to view the codes but none popped up, it could have been my technique. I drained the fuel filter and let it fill up again because i figured there might be some water in the fuel or something. I started it back up, and went on. The CEL cleared and it went away. I was scurred at first because all i could think of was the worst.
