5 Signs Of A Defective Spark Plug In Your Car

A spark plug is a very important component in a vehicle that supports fuel to ignite the combustion chamber. A bad spark plug is a big problem that can cause multiple damage and affect the performance of your car. As a long-standing integral part of the internal ignition system component, it receives a high voltage electrical current that forms the ignition coil to ignite the air or fuel mixture in the combustion chamber. This constant burning ensures that the car moves quietly on the road.

Engine failure

If the car stops while driving, engine damage has occurred. That is, there is a problem with a spark plug that may not work
properly. It may be damaged at the spark plug wire or its tip, which is connected to the conductor. During the break, the car releases many gases and emissions. It also reduces fuel consumption and reduces engine power.

Rough idling
Idling works while the vehicle is running. If the engine is working properly, the spark plugs should be continuous and smooth. If it does not work well, it will produce a rough and jumping run. Usually it feels like vibration and jittery sound. Therefore, it is not good to have your spark plug damaged because it is dangerous and more expensive.

Slow acceleration
Bad acceleration is a sign of your vehicle requiring a new spark plug. In this situation, pressing the accelerator does not set the vehicle speed. It seems to be overcharged. As the efficiency of the spark plug decreases, the acceleration of the vehicle is significantly reduced.

Problem while booting

This is the most common symptom and the simplest symptom if you need to replace the spark plug with a new one. It's hard to start the engine, even if you try several times. This is because the spark plug does not generate a spark. A bad spark plug can cause a quick discharge, which means it needs to be replaced.

Too much fuel

The main function of a spark plug is to burn fuel in a burner efficiently. If the spark plug is not working properly, the spark plug gap is automatically too small or too large. This makes combustion more inefficient, resulting in high fuel consumption.


Do not wait until the spark plug is damaged or worse if the vehicle is completely damaged by a faulty spark plug. Avoid problems by knowing the symptoms of 5 bad spark plugs. Thorough inspection can as well prevent unnecessary cost.
