Ok I know some people are gonna laugh at me because I thought the truck was fixed a couple days ago but anyways I was driving along today just cruising on down the road at 55 and out of nowhere the truck kinda hiccuped and just took off and picked up speed very fast and the check engine light came back on so i let out of the throttle and everything was fine, and when I stopped at lights and took back off it had enough power to throw me back in the seat (which it has never done) and I had to make a stop so I shut it off and when I started it again it was driving like it was before the hiccup but the check engine light was still on and I'm wondering if anyone has any idea as to y it did this?

 

Can you get a code reading? Might be that the ECM is tiddlywinking around on you. It could also be the PMD too. I want that to happen to me for once, I never get thrown back into my seat,. Quick fix if it is the ECM is to just disconnect both batteries and reset the computer, it seems to work for me. I doubt its a permanent fix, but it might be.

 

Well don't be too upset the "threw back in my seat" thing was a figure of speach meaning it had A LOT more power for those few minutes

 

Fuel solenoid armature sticking in the IP or PMD failure.
