Replaced 02 Sensors still throwing code
I have a 1998 C1500 Silverado, I just spent a pretty good amount of money to have my truck tuned up, catalytic converters replaced, and changed spark plugs. After all of this it was throwing an 02 Sensor code. I replaced all four, up flow and down flow and it is still throwing a code. I reset my battery and drove it around and the engine light went off for a while but then it eventually came back on. What could be the problem? I am stumped and I have been running around with my tags out because I cant get it inspected.

What is the actual code? There’s at least 8 codes for O2 sensors that I can think of off the top of my head and the direction diagnosis needs to go depends on the code.
If it’s bank 2 then it’s going to be P043x with “x” being the last digit of the code.
