Spark plugs play an integral role in the internal combustion process of your vehicle. Therefore, without them, your engine will not be able to produce power to move your car. Spark plugs are responsible for igniting the combustion chamber where the air and fuel mixture sit. And similar to most of your other car parts, they require routine service and replacement over time. Your spark plugs should be clean and free of any damages to achieve smooth and seamless engine operation.
Dirty or faulty spark plugs can majorly impact your engine's running ability. An engine spark plug can go bad by getting covered with fuel, oil, and carbon. Spark plugs can also blister from exposure to high heat.
Symptoms of a Bad or Failing Spark Plugs
Over time, your spark plugs will naturally wear out. Below are some of the common signs that indicate you need to replace them soon:
- Engine Misfire - Faulty spark plugs often lead to engine misfires as they cannot completely ignite the fuel and air mixture.
- Rough Idling - When the engine is running with good spark plugs, it should be smooth and quiet. However, faulty spark plugs can make your engine sound run rough, especially when idling. Additionally, you may also get random vibrations throughout the car.
- Hard Starts - Your vehicle will not start if your spark plugs cannot produce the spark to kick start the internal combustion process.
- Low Fuel Economy - Worn spark plugs will also lead to an increase in gas consumption. You may notice up to a 30 percent drop in your vehicle's MPG.
- Weak Acceleration - Finally, faulty spark plugs can also make your car lose its "quickness." When your vehicle loses acceleration power, it also burns more fuel.
Spark plugs are relatively easy to replace, so you have no reason to put off a needed replacement. Continuing to drive with bad or fouled spark plugs may result in more problems later in your vehicle's life.
