The 02 sensor on my 95 is behind the radiator and transmission cooler on the exhaust manifold. you cant miss it once you get the radiator and tranny cooler out of the way. Kind of a bitch, though.
The '97 is OBDII. There are 4 different O2 sensors on the '97 Cadillac. http://www.airbagcrash.com
It screws into the catalytic converter.
On a 2000 Cadillac Eldorado, the O2 sensors are typically located in the exhaust system. There are usually two sensors: one is positioned before the catalytic converter (upstream O2 sensor) and the other is after the catalytic converter (downstream O2 sensor). You can find them on the exhaust pipes, near the engine and the catalytic converter. For specific locations, it's best to refer to a repair manual or service guide for detailed diagrams.
A defective O2 sensor will not prevent the engine from starting. The engine will start and run albeit not as it should.
You did not specify which O2 sensor it is. Is it sensor 1 bank 1, sensor 2 bank 2, sensor 2 bank 1, or sensor 1 bank 2. There are four O2 sensors on a mazda 626

If you are replacing a 02 sensor with a new one I would cut off the wires at the sensor and slip a 7/8" box wrench over the sensor and remove it with a counterclockwise motion.

Depends on what the problem is or what code was set.
my 94 eldorado has it in the dash board glove box.
