I have an 05 F-150 5.4. I was running about 60mph this morning when all of a sudden a lost accelleration and the wrench light came on. I pulled to the side, the truck would idle smooth, but wouldn't accel. I turned it off, then started back up and ran fine. The wrench didn't come back on when I restarted. Has this happened to anybody else?

 

Sound like your truck thur a freze frame data code. The pcm stores these and i dont know why they come and go? I have a snap on brick and ive had a smiller thing happen in my 01 Expo

 

Something happened with the fly by wire throttle control. Check the code.

 

I'm leaning toward the throttle control. I'm going to stop at AutoZone this week and see if can pull a code.

 

I took the truck to the dealer instead of Auto Zone. The dealer said there was no codes in the computer. Everything came back clean. Picking up truck Friday afternoon, get more info. then.
