How often does my Mazda Miata lose power?
Occassionally, I start my ’99 Miata and the engine idles poorly, it revs up with difficulty, but it runs. Then I take it out on the highway, and after 10 minutes it starts losing power and the catalytic converter gets so hot I can smell it inside the car. This happens once a month. The runs again the next day.
What’s the problem with my Miata starting and stalling?
It is the Cam Position Sensor (CPS) and it appears to be a common problem. Many websites have information on this and several of them refer to Miata.net where you can find all kinds of Miata-based information. Here is a link of what someone wrote about our same problem:

Why does a bad catalytic converter smell like rotten egg?
A properly working catalytic converter will convert hydrogen sulfide into odorless sulfur dioxide. When failing, you may notice a sulfuric, rotten egg-like smell coming from the exhaust. Unburnt fuel left in the exhaust by the bad catalytic converter produces the odor, and may even cause dark exhaust smoke.

Why is my catalytic converter not working properly?
A technician can determine if the sensor is responding as it should. Other engine problems, such as fuel trim running too rich or too lean, oil or coolant burning, or engine misfire problems could all lead to catalytic converter contamination or premature failure.
