Replace throttle position sensor in 91 Oldsmobile cutlass?

To replace the throttle position sensor (TPS) in a 1991 Oldsmobile Cutlass, first disconnect the negative battery cable to ensure safety. Locate the TPS on the throttle body, typically held in place by two screws; remove these screws and gently pull the sensor off. Before installing the new TPS, align it properly with the throttle plate and tighten the screws securely. Finally, reconnect the electrical connector and the negative battery cable, then start the engine to ensure proper operation.
