To install a throttle positioning valve on a 1997 Cadillac, first disconnect the negative battery terminal and remove any components obstructing access to the throttle body. Remove the old throttle positioning valve by disconnecting the wiring harness and unscrewing it from the throttle body. Install the new valve by reversing the removal process, ensuring all connections are secure. Finally, reconnect the battery and start the engine to check for proper operation.
