o2 sensors are screwed into your headers. If you still have factory headers, they can be hard to access from what I've been told. I'd recommend getting a proper o2 sensor removal tool.
Usually when your o2 fails, the car will go into open loop, and the engine should idle and drive ok. So what happens is, the car will miss and stumble if the o2 is giving it bad reading, then you'll notice the engine will idle fine again as soon as it switches back into open loop. Except, will be running very rich and fuel consumption will go up.
