Okay, I feel edumacated now... ^_^

Frank;

   Thanks for the description. I kinda figured it was something like that,
(or resistive in nature) so I'm fairly clear on what's happening. What I'm
not so clear on is whether 8 cylinders or 4 would make a difference to the
computer. In theory, the *ratio* of exhaust/O2 remains the same no matter how
many cylinders are firing. The amount of O2 would increase (obviously) with
more cylinders as the exhaust volume increases. So if the computer sees that
it's dumped fuel amount X into the engine and sees only the voltage back from
the sensor for half of the normal amount of O2: well, I guess you'd have a
problem real fast. The question becomes:

   If you linked 2 separate O2 sensors (one on each exhaust system: in that
stratigic spot[however that's calculated!) so that their combined
(additive) voltage is returned to the computer: would the computer see that as
accurately as in a single exhaust system?

   All of this becomes moot if the O2 sensors are on the exhaust manifold (or
headers) doesn't it? I suppose if they follow the catylitic converters though
it becomes real critical. Now I have a headache... >_<
