I have a 2000 Cadillac Escalade, and it has a misfire, and stalls every once in awhile. It's throwing 4 codes, 3 of which are o2 Sensors codes P1153, P0155,P0161, and also a P1245 Plenum switch over code. I think it's possibly my cats?? But im not sure any input would be greatly appreciated.

Replace the 02 sensors then clear the codes and see if any come back
