Catalyst effieciency does not mean the o2 sensor is not operating correctly. Cat effiecieny means something before the o2 is not correct. The sensor is doing what it should be and picking up a problem with the mixture.

I have only ever seen a 02 sensors fail for the heater circuit or if there was no other problems that can be found in the car. But in his case the car is stalling.
