Sorry, I didn't get to reply sooner, I may have saved you some work.  My
'86 syncro GL was running rich, really rich, even getting gas in my oil.  I
thought that maybe a sensor or vacuum leak or some big problem.

Dealer said it was likely the fuel pressure regulator. . . Whaddaya know,
it turned out it was the fuel pressure regulator!  Dealer price was about
$175 (canadian) but I got a BOSCH one from local auto parts guy for $90.
Seems to have done the trick.

Hope you solve your problem, hope I helped. . .
