How Do I Know if My Spark Plugs Need Changing?

The spark plug is part of the lifeline of your vehicle, without them, your vehicle won’t start. So it’s important to know how often should you change your spark plugs. Even before electric vehicles were popular, electricity was an important part of a vehicle’s operation. The spark plug creates a spark to ignite the gasoline in the engine, which causes it to power up.

The number of spark plugs you have depends on how many cylinders are in the engine. A four-cylinder engine will have four spark plugs while a V6 will have six spark plugs. Some models offer two spark plugs for each cylinder, which provides even more precision when starting up.

For the spark plug to work correctly, it must have a gap. Spark plugs are set with a spark plug gap tool. Otherwise, the part won’t function accurately and it won’t allow the air and fuel mixture to ignite.

How Often Are Spark Plugs Changed?

Of course, you would like to get the full 30,000 miles of use from your spark plugs. But is this always how long spark plugs last? It depends on your vehicle. However, if they are beginning to cause problems, time should not be a consideration. Replacements are very affordable and will eliminate all of the following issues you could be noticing:

  • Your vehicle is slow to start or will not start.
  • The engine is running rough and does not sound or feel like it is running smoothly.
  • The engine is misfiring or not running consistently.
  • The engine does not idle smoothly or sound normally.
  • You notice that your fuel consumption is increasing for no apparent reason.
  • You feel a lack of power when you try to accelerate.

If you are experiencing any of these common issues, contact your nearest Bob Moore Group Service Center to schedule an inspection.

Your check engine light on the dashboard may come on when the spark plugs aren’t functioning as they should. It may indicate that the plugs themselves need to be replaced or the spark plug wires or coil packs require replacement. Of course, other issues with your vehicle can cause the light to come on, so it’s best to bring your vehicle to our service teams to have it diagnosed. Our service technicians have the equipment to read the codes that are present when the check engine light comes on. They will be able to tell you if changing the spark plugs will fix the problem.
