At lunch today I took my syncro for a drive and it died in  under a minute.
pulled over, disconnected the o2 sensor wire, and it fired  right up.  At
lunch I got another O2 sensor,kept looking longingly at the  O2 sensor for my
scuba rebreather on the seat next to me, it sure as hell cost  less than that
bosch part!  I'll install tonight, looks like the  problem is solved.

So now I know a little bit more about my engine.  Thanks to all who  took the
time to write.
