4 Symptoms of Bad or Failing Spark Plugs

As the name suggests, spark plugs create a spark at a predetermined time that ignites the fuel within the engine's combustion chamber. A machine with fully functioning spark plugs uses fuel efficiently while failing spark plugs causes some problems. Here are some of the things you may encounter if your car's spark plugs are damaged.

Failure to start

Failing spark plugs will not emit the spark necessary to start the engine, leading to a vehicle that doesn't start at all. Although this is a common complication of bad spark plugs, other faults may cause the engine to fail to start as well. When in doubt, it is best to consult a qualified mechanic.

The engine misfires

The ignition system of the engine relies on spark plugs and sensors to start the motor. In the event of faulty spark plugs, the engine may misfire, commonly described as a sputtering sound. Misfires are not only harsh on the ears, but they also lead to inefficient fuel consumption and increased air pollution.

Worsening fuel economy

The efficiency of your car's motor determines your car's fuel economy. If your vehicle should have failing spark plugs, the engine will misfire and not run efficiently and not use fuel efficiently. You may experience a drop in fuel economy and you will need to fill up more often than usual.

Sluggish responses

The ignition system is responsible for the acceleration of your car. If your car struggles to pull away or accelerate, it may well be that there is a fault with the ignition system that can either be an issue with the sensors, the car's computer, or the spark plugs. Owners should keep in mind that other faults may cause this problem, too, so it would be best to get a mechanic to review the issue.

Spark plugs are an essential part of the ignition system and ensure that the engine starts and runs efficiently after that. A failing spark plug will likely cause the problems mentioned above and should prompt further investigation to determine the cause and solution.
