RE: Moment of weakness...
The car should run fine without the frequency valve and the O2 sensor - my
car doesn't even have either hooked up at all (my frequency valve is
broken, actually). When you unhook the O2 sensor, it should run a little
richer, but not rougher. I would take this as a sign that perhaps your
fuel mixture needs adjusting.
