How in the hell do I take my O2 sensor off. Is there somekinda tool?
Go down to local auto parts store and rent or buy the tool. Its just like a deep socket but with a slit down the side for the wire.
you can also use a 22mm wrench…and use the 10 point side.
man… those things can get tight…
…luckily for me, I replaced my header when I replaced my O2 sensor so i never had to take it off…
make sure you put some anti-seize on the new o2 sensor though, that will help you get it off next time.
