Please post the actual ODB code you are receiving.

Shark Attack

Code would help.
If you want to just start to toss parts at it. as most people do. start with O2 sensors.
I have a blue tooth hyper tough OBD reader on every car I have. I leave it plugged into the port. It sends data to your phone. Including live sensor data as you drive and will record the data. For the price they are awesome.
Go buy one, plug it in, reset your code, record data until it gives a CEL. Review data.
You could also try swapping the 02 sensors from bank one to bank 2 and see if the issue follows the sensors.

Good luck.
