In the exhaust pipe up near the front of the catalytic converter . I think a VR only has one O2 sensor.

VR only has one, yes, and it is in the straight section of pipe just in front of the catalytic converter.

Sorry, vr commodore V6.

I never replaced an o2 sensor before, is it hard to get to? I.e. do I need to jack the car up or take out any parts that in the way?

Look under the car about level with the front doors, you will see a small muffler looking thing that is bolted in with two bolts front and 2 bolts rear, that is the cat. Just in front of that you will see a small cylindrical metal thing with a wire coming out of it, that is the O2 sensor. Follow the wire until you come to a plug, disconnect it, undo the sensor (22mm I think from memory) and screw the new one in and reconnect it. Reset the codes in the ECU by removing the engine fuse under the bonnet and turning the key to 'on'. Happy driving.
