It's nice to read your messages because you know what you're talking about and are correct with your words.

I don't know the answer to your last question..

On the older CIS systems as I understand it and listen to it, unplugging the O2 sensor leaves the frequency valve (inline injector) just buzzing away returning fuel to the tank at one frequency all the time accept maybe at full throttle.

I have it disconnected on my '87 930 and it idles smoother/better that way, but have thought about reconnecting it and tapping into the lambda harness under the seat and wiring in a switch to disconnect it there.
That way I could enable it during highway driving and maybe get 1 or 2 more miles to the gallon of gas.

Too many more important things though and may never bother doing that.
