Look on the "back" of the engine, find your rear spark plug wires, specifically the middle one, and look below it, there should be the O2 sensor screwed into the exhaust. that's as best as i can describe it

When / if you replace it though,soak it down good with some PBblaster before you try to remove it and pick up an ac delco. Bosch doesn't seem to agree with our cars

X2 on soaking with PB Blaster before removing it.
When I did mine with a Denso direct-fit, I sprayed the sensor, drove a mile to the parts store to rent to special socket, drove back, sprayed it again, waited 10 minutes for the engine to cool, then popped it right out. Counter guy at the parts store couldn't believe I was returning the socket 40 minutes after renting it.

^ Ditto to that, but I just used an open-end 21 or 22 (I forget)mm wrench. Took me longer to dig around the garage for the right tools than it did to take out the sensor! YMMV, though.
