What’s an ignition coil? How much does its replacement cost?

Have you ever encountered your car not starting in the morning? Or the car doesn’t seem to have the same levels of grunt and power as usual? And does it stall, misfire, rough idle, or get worse gas mileage than it used to? Most of the reason could be your ignition coil, which helps turn the low voltage output of your battery into the little sparks.

Let’s talk about what’s an ignition coil?

The ignition coil helps to start a car’s engine. It’s an essential part of the ignition system which transforms the battery’s low voltage into thousands of volts and needed to create an electric spark in the spark plugs to ignite the fuel. All the components in the ignition system go through lots of wear and tear, so at some point they will malfunction and need to be replaced. The components are like human heart system, if not checked regularly, the small part like an ignition coil problem can damage other parts of the car.

And do you know about wires for ignition coil?

If the engine stops and starts erratically while driving, you may have a bad wire between the ignition coil and the distributor. You can take the following precautions to avoid a faulty coil: regular service checks, regular spark plugs check and make sure the coil casing no oil leaks.

The location of the ignition coil varies from vehicle to vehicle, so check your vehicle’s user manual or use a search engine to find where your car’s ignition coil is located. You can use a spark plug tester tool to test ignition coil. If either is out of specifications, the coil needs to be replaced.

A ignition coil connector is an especially molded plastic component with electrical connections, which enables the individual cable to be connected by pins. The method of connection will vary according to the vehicle and the type of connector used.

You should constantly check and clean ignition coil connector, spark plugs and wire to prevent circuit shortcut.

How long do ignition coils last?

Ignition coils fail for a variety of reasons including high heat, vibration, or issues on the secondary side of the ignition system. Excessive heat and vibration can cause the insulating material to break down and create internal coil failure. Many coils are designed to last 100,000 miles or more; though the insulation in the ignition coil wears over time.

When electrical components get hot which typically is due to a high level of resistance. Excessive heat and vibration can cause the insulating material to break down and create internal coil failure. Worn secondary ignition components such as spark plugs or wires can cause a coil to work harder, require more voltage, and therefore significantly reduce the operating life of the coil.

You will have poor gas mileage performance when the coil begins to go bad and becomes poor to transfer power. When your car requires more fuel to run, this means you will spend more money on gas than normal.

What are the symptoms of a failing ignition coil?

Most engines have at least four ignition coils, sometimes grouped together in a coil pack. If you have problems with your car’s ignition coils, it could affect your car’s performance. This is why it’s important to be alert for the symptoms of a faulty ignition coil

The common ignition coil symptoms are engine misfires, rough idle or poor fuel economy, and a decrease in car power, especially in acceleration. You can check if the engine light is on or difficult to start the engine.

When one ignition coil fails another isn’t too far behind. If your coils are easy to access, replacing the ignition coil pack as they fail is OK.

Faulty ignition coil packs aren’t capable of delivering enough power or generating enough current for the spark plugs via ignition coil boot.

And if your ignition coils failed as a result of worn-out spark plugs, you should replace both components at the same time.
