Hi all,
   I have a inline 4 cly. VW enigne in one of my syncros with
cis-e fuel system.  Problem: ran great for first 5 thousand miles.
During a long trip it started missing, with a rough idle.  The
fuel system is out of a 1988 Vw fox.  I've replaced a ton of parts
and nothing has helped.  The o2 sensor reads less than .1 Volt
at idle. Reving the motors it climbs to .65 Volts and then
down at higher RPM's to around .4 Volts.  The spark plugs
show a lean burn condition.  Any guesses.  Anyone have this system
in anything else, care to comment?
