On RWD convention calls for orientation from driver's position, so the right cylinder bank is on pass. side of car. On our FWD cars engine rotated 90 degrees right so right bank moves next to firewall where it's also now known as the rear bank. 98 Mystique LS v6 atx 163,000km 97 Contour LX v6 atx 163,000km

I wouldn't mess with replacing only the one that is giving you the code though. Chances are the other one is not working well either. You'll notice a jump in gas mileage when you change them.
