The parts I'm talking about weren't used - just the usual stuff you get
at NAPA. I did buy a front bumper and the those energy absorbing bumper
thingies from a junkyard though. My wife crashed into a car and pushed
it into another car. The Cavalier sustained minor damage. I was a bit
shocked to find that the G forces were enough to bent the filament
backwards on the bumper mounted lights. That was a pretty good bumper.

Most anybody would get better MPG than me - I don't take long trips.

Yeah, I know. I just left off the sarcasm marks. Couldn't resist. ;-)

Well, that's my fault - I tend to take things literally. That's the
breaks. :-)

The question was "why".

And the answer is complicated.
You can do a lot with carburetors, but you cant get the instantaneous
corrections
on many levels that you can get with computerized fuel injection.

In addition, the engine, transmission, etc all have to be working together
to get
the best mileage, a feat that was not normally common to simple carbureted
systems.

The throttle chokes off the air to the engine. If there is no air, the
engine can't make power, no matter what else happens.

If you entrust air delivery to the computer and something goes wrong and
excessive air is admitted, all the other inputs will adjust to suit so that
the mixture remains correct. That means more power when power is not
wanted.

A simple cable connection is the safest and most reliable way to control
the power of any road-going automobile engine. Don't want power? Take your
foot off the gas.

And I don't care if airplanes have had wire-everything for the last 50-
years or whatever. Road-going passenger cars are given none of the sort of
scrutiny and highly-competent maintenance and inspection that airplanes are
given regularly.
