P0133 CODE WONT GO AWAY!

2001 Toyota Corolla • 194,000 miles

Hello:

I have a code p0133 that wont go away. So, far I have replaced the following: 2 sensors before and after catalytic converter and before. Used Bosch brand and wasn't sure if it matters OEM denso, or Bosch is fine. Also, I have replaced the catalytic converter and put a universal unit on. But the light with the description of : slow response bank 1 unit 1 will not go away. Can someone please advise what is going on with my baby car?
Thank you, Matt

Check for an exhaust leak and inspect oxygen sensor wire for frayed/broken
