Where is the oxygen sensor on a 95 Geo Metro?

It will be screwed into the exhaust pipe somewhere between the exhaust manifold and the catalytic converter. Most likely on the front of the engine on the bottom, sticking out fron the pipe with a wire coming out of it. some were after the cat converter. my 94 is before the cat converter, but the 94 is also a split year I think. I dont know which way they were moving them (before or after). Mine sticks straight out of the exaust pipe about 6 inches below where it mounts to the manifold. If it were after the converter it would definatly be under the car on the exaust pipe.
