O2 sensor question

I have a 95 d90 and it runs great upon startup for a few minutes, then very rapidly runs horrible (bucking, sputtering, no power, etc.). The On Board Diagnostic box reads only one code, Right O2 sensor fault. Any chance this is actually it? I have read that the O2 sensors on these are heated and work best when they warm up. I personally think it would have to be a temperature sensor that is failing, not an O2 sensor. Any thoughts are appreciated. thanks.

Disconnect the O2 sensor and see if it makes a difference - mine drives fine without but tends to want to stall at low revs.
