So! From the Top!?

I traded my '88 F150 4x4 for this 1994 F350 Crew Cab 5.8L with e40d. I drove it for two days and ran like a champ, started it up one morning and it through a code, CEL came on and it idled high and shifted hard. Checked the codes and it came up with a 122 for TPS. I changed the TPS and left the battery unhooked over night, hooked it back up and it still had the high idle with code 122.

I know i installed the TPS correctly and the pins are sitting in the same spot. Could it be a bad computer or bad electrical?

Tired of it! Wanna burn it to the ground!

Truck is nice, interior is clean only has 110K miles with a straight body...
