There are two electrical items that are part of the pedal assembly:
The Idle Validation Switch (IVS) and the Throttle Position Sensor (TPS). The IVS has a two-wire connection and is a normally open switch and closes just off idle position. The TPS is basically a variable resistor and has a three-wire connection. A quick attempt to fix can be tried by using some electrical contact cleaner on both items. Make sure you do it with the key OFF (better yet nowhere near the ignition). If that doesn't work, you would need to do some investigation on whether it is the IVS not closing just off idle or if the TPS is faulty (resistance change should have no "gaps" while cycled). Ford did not service the TPS and IVS separately. You had to buy the entire pedal assembly. For the TPS, you can try the aftermarket Dorman 699-200 for the 94-97 trucks. The IVS is very hard to find separately. You can try searching for posts by Desert Rancher who posted on a source for it (even then it may not be available). Cheers!
