With modern fuel injection systems any time you take your foot off the gas the injectors will turn off until a preset RPM is reached and then they will turn back on. On the cars I work on the turn back on point is about 1800 RPM cold and say 1300 RPM hot.
So if you take your foot off the gas in neutral the engine will get zero fuel for that split second it takes to get near idle.
