If 84 is the same as 89 there will be 5-7 wires (grounds) attached to the lower bell housing bolt on the drivers side. Some of them are grounds to the ECM.

Whoever said to replace some of whats been replaced was playing a guessing game. It would be very unusual for the ecm or eprom to give only that fault when they fail.

Was the new tps adjusted correctly when it was installed? (Most likely was just want to be sure)
as well as noted about grounds above check continuity from the tps back to the ecm on all wires
