Could be. However, often the O2 sensor failure is not detected by the computer. It can get sluggish. As far as a shotgun approach it is cheaper to try than the cat. Also I think it is more likely. Most cats are replaced because they rattle apart as far as I know. As long as the O2 sensor is fairly cheap I would throw one in. The Bosch ones are kind of spendy but the universal ones are 30.00-45.00. But I don't know how you pick a universal one since I have seen 1 wire, 2 wire, 3 wire and 4 wire... Maybe he could get the O2 sensor tested for a reasonable price?
