When I saw this discussion I peered under the van to look at the OS and was
surprised to see that the wire to it was cut off!! Now I do not have any
driveability problems or any poorer milage than any of the other postings so I
wonder if I should reconnect it or leave well enough alone? Maybe some PO found that
the OS was bad and decided this was an appropriate fix
Thanks for any comments
