And the loser is.... the oxygen sensor and the winners are those who
suggested that I remove it from the loop.

I just went for a five minute test drive and the van drove great.

Now, what's the downside of running without an O2 sensor? There must
be one. Mileage?

I think I even have a good one somewhere. I usually replace them every
couple of years but I never knew why. I do now! The last one I took
out is probably good and I think I saved it. In the time it takes to
find one or buy a new one, I wanted to know if there is a danger in
driving with it disconnected.
