In this article, we’ll be talking about Ignition Coil Symptoms, but most engines have at least four ignition coils, sometimes grouped together in a coil pack. If you have a problem with your car’s ignition, it could affect your car’s performance. This is why it’s important to be alert for the symptoms of a faulty ignition coil. Which n this article we are going to give you the basic required information you need.

Ignition Coil Symptoms

The main purpose of an ignition coil is to convert 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 will cost a range of mechanical and performance issues. The following signs or symptoms will make you notice that your vehicle has a faulty ignition coil.

Ignition Coil Symptoms

Ignition Coils send high-voltage electricity to the spark plugs, which is necessary to start the engine. most cars made in the past three decades have one ignition coil, or coil pack, per cylinder. A failing coil can result in a number of problems, such as a stalled vehicle, rough idling, or vehicle failure just to name a few. The main reason for an ignition coil is to convert the low current from a car battery into enough power to ignite the fuel and start the engine.

An ignition coil is an induction coil in an automobile’s ignition system that transforms the battery’s voltage to the thousands of volts needed to create an electric spark in the spark plugs to ignite the fuel.

Types of an Ignition Coil

There are a lot of different types of ignition coils that should be aware of when you want to fix ignition coil problems. Below are some of them.

The most common system, with multiple coils, is coil-On-plug (COP). There is one ignition coil per cylinder, with each coil connected to the spark plug.

What are the symptoms of a Faulty Engine Coil?

A failing engine can result in some symptoms but in this guide below we will be letting you know the symptoms;

  • Check Engine Light On: the check engine light will come on if your vehicle misfires or is hard to start. This problem is often caused by a malfunctioning ignition coil.
  • Poor Fuel Economy: if you notice that your car is getting less mileage from a full tank than normal, this could mean that you have a bad ignition coil. This takes place because, when your, spark plugs aren’t getting a certain power, the system will try to compensate by taking more fuel.
  • Hard Starts And Stalling: the ignition needs to spark at just the right time for the engine to start and a vehicle to run. If an ignition coil is malfunctioning and not delivering the required voltage to the spark plugs, you will find it hard to start the engine.
  • Misfiring Engine: A malfunctioning ignition coil will cause your vehicle to misfire when you accelerate. In some other cases, a misfire could cause your vehicle to shut down while you are driving.

If the coil is failing, you may hear arcing from under the hood, which sounds like a rubber band snapping. The ignition coil may look burned or white where the terminal connects to the insulated wire.

When Should I Replace a Faulty Ignition Coil?

As soon as possible. This type of failure will most likely leave you stranded on this side of the road. Even if the car still runs, misfiring may damage other parts of the engine. what you should do is find a reputable mechanic and set an appointment as soon as possible. Most coil replacements can be done the same day, but sometimes do vary between makes and models.

Some carmakers recommend replacing the ignition coils at scheduled intervals; this schedule should be followed to reduce the likelihood of failure.
