Sounds like you're confusing hybrid vehicles with non-hybrids. An automobile engine requires fuel to run, even at idle.
At idle, yes, but during engine over-run, not always--many times it will cut fueling as you coast along, until engine rpm drops below a certain threshold. Then it will start fueling again. I suspect every maker does it differently, so one really would have to hook up an instantaneous mpg gauge to see what is going on for the vehicle under question.

my son has a civic 6spd. The injectors make a lot of noise. Even in neutral, if you rev the engine, once the foot's off the brakes the injectors hush until it hits idle speed and they start chattering again. Does it when warm, consistently. Impressive de-fueling strategy.

That seems to be a problem with Cavaliers. You just can't kill them, even if you try, so you end up stuck with them!
