There is some conflicting info there. Your getting codes for both rich and leans condition so if you are correct about the code numbers, then you likely started with a severe rich condition that eventually clogged the O/2 sensors to the point they can only read lean.
At this point you probably have ruined the O/2 sensors due to driving it too long with a rich condition. Your going to have to start with new O/2 sensors and then look for the original problem. Clear the codes after the sensors are replaced and then see what codes reset after replacing the sensors. Then you'll get an accurate picture of what may be the root cause of the problem.
