O2 Sensor issues 850 1995

I recently took my 850T to the dealer for check engine light. The said, "Fault traced ECM and found multiple misfire codes, check plugs, ok. Note: Monitored front O2 sensor and found it slow to respond, recommend front O2 sensor, EST. 391.60 plus Tax."

So they reset my service light and it came back on. This time, I went to Bay 13 and learned how to read the codes myself. The only code was 425, which sounds like it alludes to the rear sensor going bad.

How can I tell which one I need to change? Should I change both, I can change both myself for less than the dealer charges me for one. Any thoughs/comments would be appreciated.
