    I have code circuit low bank1 sensor 1 P0031.Also P0420catalyst system efficiency below threshold bank 1. I had a bad muffler and the sensor back by the muffler was loose but was tightened back up. I cleared both codes and test drove still had engine issues and engine light came back on.
    What are the next steps I should take to fix? Replace the sensors?
    Thanks for the help.
