if its like the trucks it should be a tbi, with one cat. im thinkin intake gasket. try spraying carb cleaner around where the intake meets the heads with the engine running and see if the pitch changes, if so it needs gaskets

He could have 4 codes just on that one o2 sensor. 2 of them would have nothing to do with the sensor itself.
bank running rich
bank running lean
o2 #1 slow response
02 #1 reading over limits. (this one I have seen myself. the sensor is reading over 950millivolts when it shouldn't be).
