What is a Spark Plug?

Your engine needs fuel, oxygen, and a spark to generate power on your Beatrice commutes. A spark plug is responsible for creating that spark from the fuel and oxygen in the cylinders of your engine. Though spark plugs will last a long time, they will need to be replaced eventually. That’s why it’s vital to learn the signs of bad spark plugs.

What are Signs Your Spark Plugs are Failing?

So, what are the signs of bad spark plugs? Here are some of the most common red flags that we see at the service department.

  • Engine Misfires: When your cylinders don’t fire properly, you might feel an abrupt jerk when the car starts.
  • Engine Knocking: Your engine can knock or clang when you accelerate because the spark plugs are not correctly igniting the fuel.
  • EngineSurging: Your engine may start and stop unexpectedly while navigating Hickman, which can compromise your comfort and safety.
