Hi,

My 90 Carat does have an O2 sensor and cat, but no OXYS light.  There is a
sticker inside the license plate holder panel that says "OBD-II Exempt."  I
guess we were also exempt from the worthless 60k mile counter light after
all.
My county does have emissions testing, and they are always surprised at how
well it passes.  When the results degrade, I'll know when to change the O2
sensor, which may or may not be at another 60k from when I put the last one
in.  I can also look at the mileage -- I get about 19 now with no ac and
mixed driving.
