Cobrajet, I've noticed the same thing and thought the injectors were also shut off. However, I recently got a bluetooth OBDII adapter that lets me monitor stuff while underway and I've noticed that I get high instant fuel economy numbers while coasting in gear but when I shift into neutral those numbers go up. It goes against what I thought DFCO was all about. Have you watched instant fuel economy while coasting? Maybe I'm missing something.
