Cut sensor wires
What problems could occur if I cut the wires for my sensor on the catalytic converter? Power loss? I know the check engine light would be on. Thanks...

Apathy Kills
Spray a fair bit of Liquid Wrench into the threads of the bung on the exhaust pipe. Let it sit for at least 2 or 3 minutes the first time.
Then whack the exhaust pipe a half-dozen times with a dense rubber mallet to break up the gorp caught in the threads.
Repeat 2 or 3 times, adding a bit more Liquid wrench as you go. Then, thread a box wrench that is a TIGHT fit around the hex head at the end of the sensor, and use a crescent wrench ( or another end wrench) to increase your leverage.
To break what's left of the seal, whap the end of the wrench with the mallet. If the box wrench is tight fitting and fully seated, it should work like a charm....
If not, fuck it all and buy a new O^2 sensor. Since you're OBD1, a GI issue sensor from Kragen or AutoZone might work. That's bound to save some $$.
Good luck.

lmao! dude go buy the damn o2 socket, you can't cut o2 wires and re connect them. Any extra resistance to an o2 wire screws up the reading to the ecu. It's cheaper to buy the tool trust me. If the above doesn't work get a propane torch and heat the bottom of the bung until it warms up( don't do this if there's liguid wrench all over it will catch fire, clean it off first) once it's hot use the o2 socket. it should come right out. Don't try a open end wrench you'll **** it up

Cant you just pull on the wires a little to get the harness out from behind the rubber grommet and disconnect it from there? Thats what I do...
When you reinstall the sensor, dont forget to put anti-seize compound on the threads so it wont seize up later...

Yes that's a good point, You could pull the pins out of the connector and then put them back later. You would have to index them so you know where they go though and you have to know how to release pins from connectors.

I didnt mean pull the wires individually....
I dont know about the OBD1 cars, but I know on my car, there is a simple plug-in-and-out harness behind a rubber grommet a few inches away from the catalytic converter and 02 sensor. I was talking about simply disconnecting that...
