Throttle position is simply another measurement that is fed into the
computer to help it decide fuel and timing parameters.



OH! I see it has to do with those "new fangled" cars with computers
in them. I quit working on engines before that revolution started.

It actually got worse before it got better. Now that they have computers
with diagnostics, it's at least possible to tell what's going on. I thought
the worst was in the late '70s and early '80s, when the carbs had 6 or more
circuits and you could hardly follow the vacuum lines around for all of the
mechanical and electro-mechanical emission-control doohickeys -- which
seemed to get out of adjustment every other week.

You'd probably find that it's not as bad as it used to be, if you decided to
take it up again. You just have to learn some new tricks.
