Spark Plugs Need to Be Maintained Periodically

The spark plug performs a huge job in delivering a vehicle’s power, performance, and fuel efficiency.

Spark plugs may be one of the hardest working parts of a vehicle. A spark plug can fire 400 times per minute per cylinder.  Car owners make the mistake to delay spark plug repair on their vehicles, even after they have failed. This is a mistake since faulty spark plugs can lead to engine damage, reduced fuel efficiency and poor performance.  Faulty spark plugs can cause “check engine” lights, misfiring, & poor driving operation. Periodic maintenance may reduce the following issues to cause breakdown. 

  • Rattling, pinging or knocking noises. When spark plugs begin to misfire, you may notice unusual noises from the force of the pistons and combustion not working properly. Pistons travel at high velocities; if the spark plug fires at the wrong time, this could lead to constant rattling, pinging or knocking sounds.

  • Hard vehicle start. If your car is having trouble starting or just feels jerky, your spark plugs may not be working right. This can lead to misfires and erratic performance.

  • Reduced performance. Spark plugs fire when you accelerate and change gears. If the spark that the plug generates isn’t functioning at 100 percent, your vehicle performance will be poor, and you’ll experience a sluggish and fuel-wasting drive.

  • Poor fuel economy. Lots of things can lead to poor fuel economy. In the case of old spark plugs, fuel is wasted because your vehicle fails to receive the proper, heat-generating spark at the right time.
