GREAT!  And thanks for adding to the knowledge pool.  I'm sorry to hear
that my perfectly operating 20+ year old Hitachi injectors with 280K miles
on 'em are junk...... Oh, dear, what shall I do?

Actually, that's not strictly true.  I've sold the car, but I still
service and maintain it, and it's still going strong, and it's MUCH closer
to 300K.  BTW, I can turn you on to a guy with a good used one.
