It is the worst code. Erase the code, and wait

to see what code will come back. Is there anything wrong with your car? Loud noise (maybe leak cat or bad cat), vabration (misfire caused by bad coil or plug). Too many things can triger this code. If you are sure your coils and plugs are good, no leaking in exhaust, then try bank2 sensor2, and finally try pre-cat. Good luck.
