How to Spot the Signs of a Faulty Coil Pack

The coil pack plays an important function in starting the vehicle and keeping it operating smoothly. A high voltage is required by the spark plug in the engine to create a spark and initiate the combustion process. The coil pack is responsible for generating the needed high voltage.

If there's a problem with this component, the engine won't start, and your car won't run smoothly. As a result, you must be aware of faulty coil pack symptoms since any issue with the coil pack will result in engine performance difficulties.

We recommend that you search online for car service in Reading and book your car in with a professional car mechanic to repair any issues.

What Exactly Is A Coil Pack?

A coil pack is a piece of electrical equipment that is part of the ignition system. The ignition coils in this electronically controlled pack are controlled by the car's primary computer. The coil pack's primary job is to increase and develop the energy required, then release the voltage via the spark plug wires. The combustion process begins when the energy reaches the spark plugs.

Symptoms of a Faulty Coil Pack

If there is an issue with the coil pack, your automobile will not function correctly. The solution to the issue of how to determine whether a coil pack is faulty is to look for the typical indications of a bad coil pack:

The engine is misfiring - One of the faulty coil pack symptoms is engine misfiring. Attempting to start such a vehicle's engine will result in engine misfiring that sounds like coughing and sputtering. When travelling at high speeds, the vehicle's behaviour will include jerking and spitting. When a car with a faulty ignition coil is idling at a stop sign or light, it will vibrate. Look for car garages in Reading and speak with a car mechanic to explain the symptoms or even better book it in for a full diagnostic check.

Engine idling rough - Rough idling of the engine is another indication of a weak coil pack. When driving, your car appears to be lacking in power. Rough idling occurs when the coil pack fails, therefore you should replace it as soon as possible after noticing this problem.

Backfiring - In the early stages of ignition coil failure, backfiring generated by your car might reveal the signs of ignition coil failure. When the unused gasoline in the engine's combustion chambers escapes out the exhaust pipe, the car backfires. It is possible that if this problem is not identified and corrected, it will result in an expensive repair. If your automobile is backfiring, you'll see black smoke coming out of the exhaust pipe.

Exhaust smoke erupts - When the car is operating, the exhaust smoke emitted by the faulty coil pack may also be identified. Instead of coming out in a continuous stream, the smoke bursts out in spurts.

A dip in RPMs during acceleration - If your coil pack is defective, you may experience a reduction in RPMs during acceleration. It's possible to tell simply looking at the RPM gauge while driving. The check engine/engine management light comes on sporadically or blinks during acceleration.

Lower fuel efficiency - If your ignition coil does not deliver enough energy to your car's spark plugs, your vehicle will have to burn more fuel and use more fuel. The only option to keep the car going is to burn the additional and leftover fuel. If your car is getting much less fuel economy than usual, you may have a coil pack problem.

Engine management light illuminates - When the engine light comes on, how do you know if the coil pack is bad? You should look at the engine light! When utilising a car diagnostic tool, the engine light will usually illuminate on your dash, and the engine code will be P0351. Scanning the error code is the simplest approach to determine ignition coil pack symptoms. You may check the engine light and figure out what the problem is with the coil pack by looking at the error number. Search for garages in Reading online and let the professional diagnose and repair the issue.

The car won't start - One of the poor coil pack symptoms is that the car won't start. If you try to start your car and it doesn't appear to start, it's likely that the coil pack is malfunctioning.
