Ok, I just went to AutoZone, the CEL just says Bank 1 / Bank 2 oxygen sensor, worn out oxygen sensor or circuit fuse or something.

I just put in a new Oxygen Sensor Up stream and Down Stream both. Reset the code. Then it keeps coming back. What's going on??

Post the exact code numbers so that we have something to work on.

Were the codes there before you changed the sensors or after?
