Spark plugs are a vital part of any vehicle. As the name suggests, they provide the all-important spark needed to start your car. The spark ignites the air and fuel mixture in the cylinders, making your engine run. Without spark plugs, your car wouldn’t be able to go anywhere at all! Here are three signs that this critical component could be due for a change.
The Car is Difficult to Start
Cars that won’t start or require a lot of effort to start might have bad spark plugs. The spark plugs might just be too worn to generate enough spark, or they might be damaged in some way. They might also cause the battery to drain faster if they’re not in good condition, so it’s important to have the car examined by a professional.
Rough Idling
The sound of your engine should stay smooth. One bad spark plug is all it takes to cause problems. A rough idle makes noise and causes vibrations throughout the car. In this instance, a rough idle is a significant sign that the car needs service as soon as you’re able to do so.
Guzzling Gas
If the fuel efficiency is going down on your car, make sure to check your spark plugs. It’s estimated that bad spark plugs can reduce your fuel efficiency by 30 percent because combustion is incomplete. Swapping out your old spark plugs with new ones can easily solve this issue.
Spark plugs may not seem high on the car maintenance list, but getting them checked or changed is vital in order to avoid problems. Visit the Lexus of Lehigh Valley service center to get your car checked out today.
