What keeps making the sensor constantly go bad. Should premium unleaded gas be used instead of regular unleaded gas like I've been using? The car shuts off while driving and then it over compensates and runs the engine too fast messing up the transmission shifting. What would cause the part keep going bad.
My car has 65000 miles.
Within conventional throttle position sensors there are metal contacts that sweep across a printed resistor board. Repetitive motion and vehicle vibration can cause these contacts to wear, over time, eventually causing sensor malfunction. If you are sure that the TPS itself, and not something else such as a loose connector, has failed in other like "repetitive part failure" scenarios, the best thing to do is buy the OEM GM part from the dealer. You should test the TPS and replace if indicated. If you want these steps performed by a certified Mechanic, dispatched by YourMechanic right to your location, please request a TPS sensor diagnostic/inspection and the responding certified mechanic will get this resolved for you.
