Before randomly replacing parts in hope that you accidentally
fix some unknown malfunction, you should perform some diagnostics. Always start with the free stuff, and then move to cheap and easy stuff. Check all the fuses. Check the fuse at or near the TCU. Inspect the wires and wire connectors for corrosion or damage. Test and inspect the sensors including the throttle position sensor(TPS), transmission output speed sensor, vehicle speed sensor, park/neutral position (NSS) switch and brake switch. Check the Throttle Valve cable, make sure it is set correctly.
