Had a pedal stick wide open on a 40K pound truck once. Was exciting for a few seconds but turned out like yours. Turned it off, coasted into a parking lot and found the problem. A bolt has backed out on theo throttle mounting plate and it had caught up on that.
hmmm...thinking about and since I'm not a mechanic any recommendations on what I should look for. Like I said, I'm pretty sure it was just a floor mat as the rest of the drive in was fine.
