Hopefully I’m wrong, but I’d be surprised if my ‘95 Civic completely cuts fuel when decelerating in gear. If that were the case, it seems shifting to neutral to coast wouldn’t be as effective. I know you coast much further if not in gear, but to fire all cylinders while coasting versus not firing any cylinders in gear, even if you don’t coast nearly as long, it seems coasting in neutral would t have as much advantage as it proves to have.

Maybe decel fuel cut is a thing for late model cars, say from 2015 or 2017 and on, but for mid 90s vehicles, even though fuel injection had been in play for ten years, seems unlikely to me.

I hope I’m wrong.
