I have a 1988 300E W124. Can someone please give me detailed instructions on how to replace the O2 sensor? Do I have to reset the engine management computer after replacing the sensor? If so, how do I do it? My car is a Canadian/US Federal version, so it doesn't have the push button/LED on the diagnostic panel next to the battery.

Thanks very much in advance.
