I had a similiar problem just after a bought my 87' Syncro.  You propably
need to adjust the throttle switch.  It is located just below the throttle
housing.  It can be adjusted by turning the two allen head screws adjacent to
the throtle body.  The Bently Manual goes into this in better detail.  This
cured my problem approximatly 20K miles ago.  No problems since.
