I’ve heard people say that fuel injection automatically turns off when you let the car coast in gear, but if I completely let off the accelerator in first gear, the car will only slow down to 3-5mph (depending on the car) and will then stay at that speed indefinitely like a lil’ cruise control, suggesting that the car was always injecting fuel at engine idle ratio?
I understand this kind of question has been asked before, but as this element doesn’t check out, I don’t believe it has actually been completely answered.

In addition to the other answers — the car completely stops the fuel injection for an indefinite amount of time if it’s coasting downhill (and maintaining speed).
