Well, when the car is new there are mileage trips for that, but that light also indicates a sensor malf. So basically just replace the O2 sensor(s) and reset the ECU (should be a button under the dash or under a seat somewhere).

My Stanza does the same... Though something I've noticed now, is that if I unplug the sensor, the light doesn't come back on. *shrug*

No do not do this

Unplug the harness under the dash that says "Exhaust Gas Sensor Unplug after 90,000 miles"

It trips after 30,000-60,000-90,000 miles- after that you should disconnect it. The harness you are supposed to disconnect is right above the ecu on the passenger side of the car behind the floor panel
