What Are The Symptoms of Bad or Failing Spark Plugs?

Getting your car ready for summer fun and noticing sluggish startup, slow acceleration, or poor fuel economy? These are all potential signs that your spark plugs are bad or failing. Spark plugs are a relatively easy fix and can help keep your car on the road longer. Keep reading to learn about how to mitigate the symptoms of bad or failing spark plugs.

How Often Should You Change Your Spark Plugs?

Maintaining the spark plugs on your vehicle is one of the easiest and least expensive forms of car maintenance. Changing or replacing your spark plugs according to vehicle or manufacturer recommendations is one of the best ways to keep your vehicle running in optimal condition.

Most US vehicle manufacturers recommend changing the spark plugs in your vehicle after driving between 30,000 and 50,000 miles. Driving your car without changing the spark plugs according to manufacturer recommendations can cause longer term damage to engine components and fuel systems that result in having to put your car in the shop and other costly repair issues.

Signs Your Spark Plugs are Bad or Failing

If your car engine feels like it's surging or hesitating when you're speeding up or rough idling and vibrating while your car is on and standing still, these are signs of a mechanical issue that could be related to deteriorating spark plugs.

Telltale signs of bad or failing spark plugs include continuous engine misfires, slow acceleration (when your foot is already nearing the floor), poor gas mileage. Most people notice there is a mechanical issue with their vehicle when they find themselves filling up more often than normal. Spark plug misfires can cause lowered fuel economy when the air-fuel mixture is unbalanced.
