symptoms of a faulty ignition coil
When a car functions properly, it drives smoothly and fairly silently. Stalling, low engine power, backfiring, engine noise, and difficulties getting the car started are clear signs that something is amiss. Because ignition coils supply power to the car's spark plugs, a faulty coil can cause any of these symptoms. If the broken coil is not replaced, it can cause long-term damage to the car's engine and exhaust system.
