strange problem-intermittent throttle problem

[stroked outlaw]

I have a 2002 f 350 and today while driving along when i let off the throttle and tried to step on it again there was no responce. It was dead, even if i pushed it to the floor, but if i let it up all the way and stepped down again, it would work normally. It also did it in park if I pressed it slowly. any ideas? maybe a pedal assy.? It seems to be getting worse.

Sounds like pedal assy to me.

thats actually pretty common. I have replaced atleast a dozen pedal assemblies.

power stroke engines are controlled by what i call fly by wire setup , no cables or linkages engine controlled by pcm which gets its signal from the tp sensor mounted on accelerator pedal inside , the higher the reading the pcm gets from the tp sensor , the higher the engine revs , the tp sensor can go bad , truck will crank but wont go any where when goes out

very easy , 3 10 mm bolts , unplug , plug back up take you just a minute

Hey Scott, can this sensor go partially out?? Or is it a situation where its either good or bad. No in between? Just curious if the first part of the pedal movement can go out and then pick up about a third the way down. Thanks.

It sure can. I actually have 3 assemblies in my tool box that I know will work well enough to get somebody home. However on 2 of them you have to smack them with your foot some times.
