How come my buddy with a z32 has the same oxygen sensor and his works just fine- are our oxygen sensors high voltage or anything? I didnt think they were- they are only three wires- of course I am new to this car and am waiting for the fsm and am really kinda ignorant with it still. I have it hooked up to the white wire and I have checked my power and ground, both are fine.
