ok thansk to your help, i got the primarr O2 off, now how the hell do i get the cat O2 sensor off?? there is no tab or anything.

the car is too high off the gournd to just drop the whole exhaust. the O2 wires will not reach the ground...any help?...

 

Trace O2 sensor wires towards chassis of car.

There will be a rubber grommet that seals the chassis. Pull this grommet out and it will reveal more wiring and a plug where the O2 can be disconnected.

Good luck.

 

reid, i can see the wires of the O2 lead into the chassis. do i just pull on this to unearth the rest of the wires and the plug? thanks!

 

Yes, sir.

Pulling on the wires will effectively dislodge the grommet and the plug will be exposed.

 

got it off, thanks brotha!!

 

using a open end wrench works too should be 12mm or 13mm i believe. instead of unplugging it from the block just unscrew it off from the cat. was easier that way for me.
