Question about Power versus Fuel Input
I have an observation and then a question.
I have a long two mile hill I drive up in my '93 Geo Metro (The Phoenix).
I go it in 4th gear and maintain 55 mph - that is about all the old girl can do !
The gas pedal is on the floor, but I notice that if I let up on the pedal maybe 1/4 to 1/2 inch,
the speed doesn't go down.
Thus, more accelerator doesn't give more speed.
When you drove an older car with a carburetor, when you press down on the accelerator,
more gasoline is dumped into the engine.
Now my question is - with the Metro, the Computer and the Throttle Body/Injector, when
the engine is doing all it can, does the computer stop adding MORE gasoline regardless
of the position of the accelerator ?
An older, carbureted vehicle would have just dumped more gasoline and made it rich.
Is my Metro's computer smart enough to keep the fuel at an optimum for the power needed,
or does it add more fuel as I depress the pedal ?
Is my question clear ?

PS - Is the Chevy AVEO worth squat ? Came out in 2004 - I'm slow on the uptake....
Is it the new Geo Metro ?
