The solution to the O2 sensor problem is in fact a heated O2
sensor. O2
sensors will not work until they reach at least 600 deg. F. No load on the
engine and
headers will cool the std. O2 sensor below 600 deg. F. Heated O2 sensors are
available at Kragen, Grand auto, etc. They're made by Bosch and are all the
same
except for the connector which you'll have to cut off. You'll also have to
cut off the stock harness connector. To install you'll have to go to Radio
Shack and get a 3 or 4 pin connector. One of the two heater leads has to go
to a switched 12V source while
the other goes to ground. You may have one or two wires from the O2 sensor now
ergo the 4 pin connector.

I've seen a similar problem reported a few times on the Miata list. It
seems to often be related to the O2 sensor not staying warm enough.
There are sensors available with a built in heating element to keep
them up to temp.
