I was installing my downpipe last night, and i had a difficult time removing my O2 sensor. From the way it looked i think i need a new one. I had to resort to cutting the wire and twisting them together and then used electrical tape to put it all back together. Does anyone happen to have an extra or O2 sensor they will not use? if so please email me at firstname.lastname@example.org. Has anyone else faced this sort of dilema?
