I have a GC25k AT82D90152, w/ tier 1 fuel system. Intermittenly, the throddle body elec. soliniod does not change voltage and doesn't allow for a rev on the engine. The pot changes voltage but it doesn't have a full.3v to 4.7 volt sweep. The machine will reset if the truck is shut down and restarted w/out touching the acc pedal. Any ideas?
It would seem as if there is a signal to the ECU not allowing for the V change

Also need a P/N for the ECU and accel pot.

Thanks
