Can't remember which bank is L and R, but regardless, sensor 1 is one of the pre-cat wideband O2's. The trick to all of this is your extensions aren't really hooked up, they just appear that way... I'd also recommend removing both of them at the same time, or they'll be off balanced.
im not following you, on the extensions not being hooked up.
any way to test the o2 sensor to see if its bad before I go and buy a new one?
also in reading through the pages sounds like strany had p0059 as well and that was his passenger side so I would assume bank two is passenger side.
