Ok. New O2 sensor, remaned carb, Idle is set at 600 RPM's. I'm still getting a CE light with a "Rich Code." The car still idles too high and if you start it warm the idle is too low and it stalls within 3 seconds of starting. I'm guessing the carb is just bad. For some reason it just says "**** the setting, I'll run rich if I want to dammit." I'm getting another remanned carb for free and trying this again. Can anyone tell me why my carb is deciding to run rich?
