I wanted to remove the o2 sensor to get the cat and resonator off in one piece. The bolts and nuts are welded together.
I borrowed a socket from auto zone but it wouldn't go on because the slit in the socket is too small for the wire coming
out of the sensor. Probably couldn't get it loose anyway. But, the FSM shows the o2 sensor wire being connected with a
regular wire connector. On my car the wire just goes into a grommet in the under carriage, no connector that I can see.
I don't need to replace the cat just the resonator, it doesn't look too easy to cut off the nuts and bolts while on the car.
What to do? Any tips?
