My guess would be that when you're completely off the gas, you go into DFCO, and there's no fuel at all being used. This is starting to make sense to me (we just bought a 2012 Civic LX, and I think it works the same way)... I think it coasts so well in DFCO because the butterfly stays open. Is that possible?
