What is an Ingnition Coil?

The ignition coil functions as part of the ignition system, alongside the switch battery, alternator, spark plugs and distributor. Your vehicle's ignition coil converts the low current from a car battery into enough power to ignite the fuel and start the engine. When there is a problem with an ignition coil, it can cause a range of mechanical and performance issues.

What are the Signs of a Faulty Ignition Coil?

The following signs will warn you that your vehicle may have a faulty ignition coil:

  • Loss of Power is generally one of the first symptoms of ignition coil failure. Your vehicle may feel sluggish, and you may experience a loss of power. This is caused by irregular sparks to bring about the required combustion.
  • The check engine light is on. If your vehicle misfires or is hard to start, your check engine light turn on. This problem is often caused by a malfunctioning ignition coil.
  • Poor fuel ecomony. If you find yourself driving the same distances but needing to visit the gas station more often, it’s could be sign of ignition coil failure. When an ignition coil fails, an incorrect 02 sensor read sends more gas than required. You will fill up more often because the spark plugs are not getting enough power, and to compensate, the system injects more fuel.
  • Backfiring. If your vehicle starts to backfire, a bad ignition coil could be the cause. A vehicle makes a loud bang sound when unused fuel in the combustion cylinders explodes, causing black smoke to emerge from the exhaust pipe and the strong smell of gas.
  • Misfiring Engine. A faulty ignition coil may cause your vehicle to misfire when you accelerate. In extreme cases, a misfire could even cause your vehicle to shut down while you are driving. The misfire is a result of one of the cylinders fires incorrectly or not at all.
  • Hard starts and stalling. If your ignition coil is malfunctioning and not providing the required voltage to the spark plugs, you may find it hard to start the engine. If your vehicle stalls when you stop and even shuts off completely, it could be a bad ignition coil sending irregular sparks to the spark plugs.
  • Sputtering and coughing sounds. If you vehicle is making spluttering and coughing sounds when you start the engine, an ignition coil may be causing the problem. A cylinder that is not firing at all during the ignition process can be the source of these sounds.
  • Jerking and vibrating. Another sign a failing ignition coil is vibrations when the vehicle is idling. You may also feel your vehicle hesitate and jerk forward when accelerating.
