I defy you to look at an instantaneous residual oxygen
reading that is lean past the end of the scale and
tell me whether the vehicle is A) not running, B)
incredibly lean, C) rich misfiring.

I can look at an instantaneous four-gas plot and tell
them apart with great ease.

Since there's no way to separate out the exhaust gases
of an individual cylinder unless you pipe into a
manifold runner, I'm surprised to hear someone claim
that.

If one cylinder is misfiring, the dignostic procedire
is quick and easy, just like it's always been (unless
it's an injector problem and you're running
sequential-fire).

I opted not to answer your other post about cooling,
since the pieces of it that were not already covered
with the opinions of others regarding cooling issues
were already responded to by myself in previous posts.
