The vehicle may lose vehicle speed signal, which can affect speedometer operation and transmission shift quality. Most often the Vehicle Speed Sensor is faulty, however, at times, the driven gear inside the transmission is at fault. Replace the Vehicle Speed sensor and inspect the driven gear upon sensor removal.

1990 Ford Tempo Problems
Sludge build up in the throttle body can cause a poor engine idle, stalling, and/or hesitation. The correction is to install a new idle air control valve spacer kit to prevent the sludge build up, set the base idle, and clean the throttle body.
If the throttle lever is out of adjustment, or the grommets are missing / broken at the throttle or transmission, the automatic transmission can shift hard. Replace the grommets as needed and adjust the throttle lever.
Outdated software in the engine control processor can cause poor engine performance, hesitation on acceleration, and possible stalling problems. The processor will need to be replaced to get the updated calibration.
Internal heater blower motor issues can cause a ticking noise from the heater blower when the fan is on. To correct this concern, replace the heater blower motor with a revised unit.
