How do you replace Mitsubishi 3000gt oxygen sensors?

To replace the oxygen sensors on a Mitsubishi 3000GT, first, ensure the vehicle is off and cool. Locate the oxygen sensors, which are usually found on the exhaust manifold and after the catalytic converter. Disconnect the electrical connectors and remove the sensors using an O2 sensor socket or a wrench. Install the new sensors by threading them into place, reconnecting the electrical connectors, and ensuring they are secure.
