Sounds like the Oxygen Sensor is good, it's just detecting the
header leak.

I agree with ßill on this one. That header leak will screw up
your O2 sensor big time and it's not doing any good for your
cat or your fuel economy.

As for the manifold, it's a fairly easy DIY project with lots
of drop-in (or semi drop-in) aftermarket solutions. Having
the service manual helps because you will need the torque spec
and sequence for the manifold.

Thanks for the tips guys. I replaced the front O2 sensor and the Check
Engine light and code "21" have gone away.

Thanks again,
