Ok. Another question:

When my car is fully warmed up and it idling at a stop, my RPM reads around 750-800rpm which turns out to be a refreshing 0.1Gallons/Hour.
However, whenever the car is in motion, say 30mph, when I push in the clutch the car likes to idle around 1250 RPM instead which translates to 0.2Gallons/Hour.

Why doesn't the engine idle at the 750-800 range when the car is in motion? It would be nice to have that 0.1GPH while coasting. Is there a way to change the idle speed? Or is there a good reason why it idles at 1250RPM?

You can bang a 50mm preserving jar cork into the air intake.
That will change the idle speed.

I think it something to do with manual trans. the computer thinks you might go back into gear while still moving.
