Bank 2 sensor 2 is the drive side, post catalytic converter. Basically the 2nd sensor from front to back. This won't cause running issues though so you are going to need to dive a little deeper for that. Make sure your spark plugs, fuel filter are up to date. Past that you will need a diagnosis for the rough running. Here is a link to find a shop near you. https://repairpal.com/repair-shops Alex
