I believe the secret of the Misfiring Vanagon has been solved and I thank
everyone who sent advice. Someone suggested that I check my ground strap.  The
funny thing was that I just noticed the day before that my ground strap was
broken.  It must have happened on my trip to Boston and that is when the
missing started.  The van also started harder than it normally did.  So I
replaced the ground strap with a insulated battery cable for an American car
that already had the ends on it and everything and was about 19 inches long.
Cost a whopping $3 and our local Farm and Family store!  So if your van is
starting harder now that it is cold, maybe you should check that ground strap
too.  It is on the left of the motor attached from the top of the head to the
firewall.  Happy driving and thanks again.
