The post-cat sensor just tells the OBD-II monitoring system that the cat appears to be working - My understanding is that the precat O2 sensor is used to adjust mixture (it worked fine without a post cat O2 sensor until 1996).
Anyway, if your temp sensor is out of whack, the ECU will supply an incorrect fuel mixture. Note that you can measure the resistance of the temp sensors at various temperatures to see if it is within spec. I'm not sure about the proper readings on a 1997 car, but it has probably been described in a previous post; you need to do a search.
