Have you ever wondered if your vehicle's spark plugs need to be replaced? Spark plugs might not be thought of often, but they play a big role in keeping your engine running smoothly. How do you know when to change them? How do you know when they need to be replaced? Let’s talk about the importance of spark plugs!
What Do Spark Plugs Do?
Spark plugs create the spark that ignites the fuel in your engine. Without properly working spark plugs, your engine might struggle to start, run rough, or even stop working altogether.
Signs Your Spark Plugs Need to Be Replaced
Your vehicle will usually give you signs when it’s time for new spark plugs. Keep an eye for these common issues:
Slow or Rough Starts – If your vehicle takes longer to start or shakes when idling
Poor Gas Mileage – Bad spark plugs make your engine work harder, which means you burn more fuel. If you're filling up more often, it might be time for a replacement.
Loss of Power – Does your vehicle feel sluggish or unresponsive when you press the gas?
Check Engine Light – Sometimes, bad spark plugs will trigger the check engine light. We can scan your check engine light to see if the spark plugs are to blame.
Engine Misfiring – If your vehicle jerks or hesitates while driving, a faulty spark plug might not be firing correctly.
When Should You Replace Your Spark Plugs?
Most vehicles need new spark plugs every 30,000 to 100,000 miles, depending on the type of spark plugs and the vehicles make and model. You can check your owner’s manual or ask our team when it is recommended to replace the spark plugs as part of preventive maintenance for your vehicle.
