I just had a look at mine this arvo quickly, been told the front one is playing up, but what did the stock RB26DETT come out with for R33? mine has o2 sensor at the rear with 3 wires, front one has only 2 wires coming from it?
which one has been changed previously? im guessing the one with 3 wires (i.e rear) has been replaced at some stage.
Now if going to buy one, are the front and rear ones the same on R33 gtr? or different part numbers?
