Re: about time to change the o2's?
An OBDI computer doesn't have any input "channels" to read the rear 2 O2 sensors, therefore the rear 2 sensors don't do anything. The rear sensors were added to OBDII cars to monitor the cats, comparing oxygen readings before and after the cat to determine when the cats fail.
Even though your high mileage O2 sensors still "bounce" from 100 mV - 900 mV, it doesn't necessarily mean they're functioning well. It's also have fast they response to changes in oxygen readings. Your car will burn rich as the sensors get coated; is your gas mileage where it should be?
