Removing the O2 sensor

This is a stupid question, but how do I remove the pass. side 02 sensor? I can't fit a wrench in there, and my normal O2 sensor socket won't fit over the thick wire. Do you guys have any tricks, or do I have to buy another stupid tool?

On that note, the actual 3 bolts that bolt the cat to the exhaust manifold are on there VERY tight. Any tricks for getting those off?

Spray the bolts w/ PB blaster and let it soak. It helps, but i still broke a few off. Of course, i had a big ass impact wrench. :D


Sounds like you're installing headers, when i did mine i left all the sensors and just unbolted everything, the removed them off the car.


Good luck
