The first O2 sensor is located just below the header/exhaust manifold, and can be seen just below the header's heat shield. It is most easily accessed by removing the driver's side wheel.
The second O2 sensor is located after the catalytic covertor between the rear wheels at the 12 o'clock position.
Because Miata engines typically run rich, it is not uncommon for the first O2 sensor to die early.

Where is the rear 02 sensor on your 99 miata?
In 1999-2000, Mazda designed 2 exhaust versions.The most common version is the Federal-spec Miata. This exhaust system has the typical, single catalytic converter with an O2 sensor before and after it.The front O2 sensor is before the catalytic convertor and can be seen by removing the driver's side wheel.The rear O2 sensor will be just after the catalytic converter, at the 12 o'clock position between the rear wheels.The California-spec Miata had a precatalytic converter directly installed on the exhaust manifold/header, as well as the standard catalytic converter running the length of the engine.You will find the first O2 sensor directly on the header, just above the pre-cat. It is easily seen from the driver's side of the engine bay.The second O2 sensor is found just below the pre-cat, but before the main catalytic converter. It is easily seen by removing the driver's side wheel.

The first O2 sensor is located under the hood in the exhaust. It is a simple matter of unplugging it and removing from the exhaust. The second O2 sensor is located under the car and the wire runs through the floor board and the connector is found under the carpet under the drivers seat. The drivers seat will have to be removed and the carpet pulled back to disconnect the O2 sensor wire. The car must then be jacked up the catalytic converter unbolted and pulled down to gain access to the O2 sensor.
