Red face help o2 sensor problems!

hey guys i did a search and found some ansewers but i still have a few questions.
i got a po155 code bank 2 sensor 1.
my car seems to be running fine no sputering power seems all there but i have to code on.
the car has pacesetter lt's and the oem front 02 sensors with the tsp extentions the rears are tuned out.
most of what i read on the po155 code had peoples cars runing bad but my car feels fine.

the 02's do have a good amout of miles and i think there the stock ones and if they are they have around a 100k on them so the car could use a new set.

should i just get the stock replacements or go with the vette 13111 02's?

i also read the the vette 13111's are rear sensore so i dont know if those work for the front of my car because i know there not interchangeable front and rear on my camaro.

help me out guys and thanks.

Bank 2 Sensor 1 is in front of the cat on the passenger side.

I think stock or Bosch (sp?)

It's probably pretty fouled up. I would replace the sensors on both sides...

just had my car throw the code for the drivers side. I replaced the sensor with a Denso O2 for a vette and the code came back. Turned out i had some wiring issues, the owner before me somehow managed to pull and yank on the wires enough to crack them(up by the valve cover...) Soldered everything back together and it seems good so far. i normally dont solder but i highly recommend soldering at least the signal and ground wire as it seemed to cure my problem because i tried butt-connecting them and still no good.
