Toyota Repair: 1992 Previa LE, throttle position sensor, engine hesitation

Question
My 92 Previa LE engine hesitate at about 50 km/h under normal acceleration and under fast acceleration, it does not hesitate. The plugs, wires are new and the transmission oil has been changed.
Thanks

Answer
Some of the previas had a problem with the wiring on the throttle position sensor causing what seemed like an engine hesitation, have the wires and connector at the tps checked, there is a repair sub-harness available from toyota that fixes this problem.
