So, is this unique to the Spit?? I drove an old Alfa-Romeo for
quite some time when I lived in Europe (back in the days when you
could still go fast in most places) and it not only had better
gas mileage than my Ford Capri, but performed quite well at both
low and high speeds. (As an aside, while difficult to do things
like valve adjustment it was one of the best engineered engines
I ever ran or worked on.)

Glad to see someone say this. It would be real hard to believe that
the guys designing the manifolds knew so little about their job.
