Re: Pedal problems

It sounds like the connector might not be connected correctly or you have a open wire. I had the same problem and it turned out I had a cut wire on the harness.

Re: Pedal problems

Seems to be a somewhat common issue....

http://67-72chevytrucks.com/vboard/s...d.php?t=553282

The APP pedal sensor can go bad as you've tried to change. Double check for any bad wiring, especially near the throttle body.

You can try to reset the codes when it happens and see if that helps. Or, turn off the truck and wait a minute.

It really sucks when this happens WHILE you are driving....

Re: Pedal problems

Little purple wire on the TB likes to crack or pull out from the pin as well. Still interested in which codes it threw tho.
