I'm guessing just replacing the 02 Sensor, could be going bad?

Hey do you happen to have a turbo? Cause i my cav is turbocharged and i was getting both of those codes. For me its cause the fuel PSI was turnned up to 80PSI (thats where you get the best air/fuel ratio). Well i put it down and the codes went away. I hoped that helped with your problem.

Bye the way nice car. I like the blue and white theme going on.
