Hello everyone been lurking for a couple years and decided to join up. I have done a lot of research on here about the cat delete process so I went ahead and did it on my 2000 silverado 5.3. Mainly cuz I was getting the 420 code, I monatered the rear o2sensors and the bank one was doing some jumping around and was reading lower than the bank 2 sensor 2, so I pulled bank one sensor 2 and cleaned it with air and carb cleaner and stuck it back in well a few days later the code came back, so I cut out the cats and did the spark plug non foulers on the back 2 sensors and today the cel came one and this time it said bank 1 sensor 2 low voltage, this may sound dumb but guessing the sensor is bad right? Any help would be appreciated thanks.
