Default o2 sensor dead ? how to tell ?

how can i tell if my o2 sensor is shot ? i guess i gotta go get the miata smogged for real. couldn't find a bootlegger in reno this time.

im running a vortech, 12:1 305cc injectors and a walbro 195hp.

if i slap a cat on and replace the o2 sensor should i pass ?

or should i swap the 305cc out for stock 1.6 injectors?

What makes you think it's dead?

and what does home made whiskey have to do with smogging your miata?

CEL light will turn on...

Typically it'll clear for a short period of time if you shut off the car and turn it back on. That's been my experience at least. Otherwise you could hit the diagnostics port and see what engine codes come up.
