Throttle Position Sensor

[Dunkun Doughnuts]

I have a 1997 Toyota Tacoma, 4 cyl, 2.7L, 4WD. My engine started...well bucking is the best word. The engine would be running fine, then suddenly die (but not stop, just go to very low power) for a second and then rev back up to full power. Made the car "buck" every time it returned to full power. Nothing on the engine diagnostic system. Figured out it was the Throttle Position Sensor through troubleshooting. I replaced the sensor, but the problem persisted. I unplugged the sensor completely, and the car works fine now. But I am not getting good gas mileage. I believe the problem could be because there is a loose contact in the cable that connects to the sensor. Maybe bent out of shape so that it momentarily loses contact, and then re-makes contact. Advice? How would I splice and then redo the cable?

I know when i had an issue with an eratic idle on my gen1 tundra it was time to clean the throttle body unit. Never had problems with the TPS.

I’m not a fan of working on electrical on vehicles. I would guess getting the same gauge wire and making it happen if you’re electrically inclined.
