A failing ignition coil can significantly impact fuel efficiency. When a coil weakens, it may not generate a strong enough spark, leading to incomplete combustion and increased fuel consumption. Some drivers notice a in mileage and more frequent refueling before realizing the coil issue. After replacing a faulty coil, fuel economy typically improves, along with smoother engine performance.
