A weak o r faulty ignition coil leads to incomplete combustion. This can cause:

Increased Fuel Consumption: The engine will need more fuel to compensate for poor combustion, resulting in lower fuel efficiency reduced MPG.
Unstable Performance: As the combustion process becomes inefficient, the vehicle may experience hesitation, rough idling, o r sputtering, all of which contribute to wasted fuel.

Replacing a faulty ignition coil can help restore fuel economy and smooth performance.
