Double check you put everything back the way it was. Fuse 3 (3 amp) protects the IVS (idle validation switch) which, if blown will cause your symptoms.
Make sure the blade from the peddle mechanism is engaged in the back of the TPS. Just ran into this the other day. If you have been down in the floor board working, and pushed the peddle over toward the pass. side, it could have slipped out of the back of the TPS. Take the TPS off and push that shaft with the blade on it back toward the driver's side, and make sure you get the slot in the back of the TPS on that blade correctly.
