Silly question: How does one remove the O2 sensor?
I can't seem to figure out the trick to getting a wrench down and on the sensor with enough room to move it. Is there some form of trick to this, or a special socket that can be used?

You should have searched this website, it's been covered recently.

A flexhead wrench/breaker bar will help with the odd angle.

You should go to the parts store and get an O2 sensor tool. Its like a reall long socket with a slot in the side for the wire to stick out so you don't break it off. I think they are around 12 bucks and will make your life a LOT easier!

Just replaced mine using an open end wrench, no hard at all. The only thing I needed to do was cut and splice a wire onto the universal O2 sensor.
Already the exhaust doesn't smell as rich, I'm hoping that this will translate to better fuel economy!

I found an O2 sensor socket at Advance Auto. I also soaked the old socket in penetrating oil before I worked on breaking it loose. I used a long breaker bar to gain some leverage. It was on tight but I finally got it loosened. Used a good dose of thread grease on the new one. Good luck with yours.
