Its common for some O2 issues to be intermittent. The normal sensor readings are a waveform and not like a simple switch or a constant reading. (such as air or coolant temp) You may be getting a code when the waveform briefly dips over or under the PCM's limits - which may occur occasionally.
What codes are you getting? Are they just on one side?
Sometimes an O2 code will be caused by a different defective emissions component. (For example, I had a dirty MAF causing intermittent P0137 and P0157 codes.)
