When it comes to the performance and efficiency of your vehicle, there are several components that play a crucial role. One of the most important and often overlooked components is the spark plug. Spark plugs are responsible for igniting the fuel-air mixture in your engine, which powers your vehicle’s movement. But what happens if your spark plugs are bad? In this article, we will explore the consequences of worn-out spark plugs and provide you with a comprehensive guide on what to do if you suspect your spark plugs are not functioning properly.
What are Spark Plugs and How Do They Work?
Spark plugs are small devices that are installed in the engine of your vehicle. They are responsible for creating a spark that ignites the fuel-air mixture in the combustion chamber, which powers your vehicle’s movement. The spark plug is connected to the ignition coil, which generates a high-voltage electrical current that is sent to the spark plug. When the current reaches the spark plug, it creates a spark that ignites the fuel-air mixture, causing the engine to run.
