On a computer controlled fuel injected car, when one lifts one's foot off the throttle and coasts in gear, is any fuel still being injected into the cylinders, or do the injectors shut off? Is spark still supplied to the plugs when no throttle is applied? Would this depend on whether the car uses a cap and rotor or not? I was thinking about this tonight, and realized that I have no idea. Many thanks to anyone who can answer my questions!!
