Your vehicle’s spark plugs may be small, but they play a critical role in your engine’s performance. Responsible for igniting the air-fuel mixture that powers your engine, spark plugs help keep your vehicle running smoothly, efficiently, and reliably. When spark plugs begin to wear out or fail, your engine's performance suffers. At Wayne's Garage Inc, we help drivers recognize the signs early so they can avoid more serious and costly engine issues down the road.
What Do Spark Plugs Do?
Spark plugs deliver the electric spark that ignites the fuel inside your engine’s combustion chamber. Without them, your vehicle wouldn’t start or run. Over time, spark plugs wear down due to extreme heat, pressure, and exposure to carbon deposits. That’s why regular inspection and timely replacement are key parts of preventative maintenance.
Common Signs of Bad Spark Plugs
Here are the most common signs that your spark plugs may need to be checked or replaced:
1. Rough Engine Idle or Misfiring
If your vehicle idles roughly or you notice jerking or hesitation while accelerating, worn spark plugs could be to blame. Misfiring happens when the spark isn’t strong enough to ignite the air-fuel mixture correctly.
2. Trouble Starting the Vehicle
If your engine cranks longer than usual or struggles to start, failing spark plugs might be preventing proper combustion. This is especially noticeable during cold starts or after your vehicle has been sitting idle for a while.
3. Poor Fuel Economy
Worn spark plugs can reduce your engine’s efficiency. If you’re filling up the tank more often than usual, your vehicle may be burning more fuel than necessary due to incomplete combustion.
4. Lack of Acceleration
Are you pressing the gas pedal but not getting the response you’re used to? Faulty spark plugs can cause sluggish acceleration and decreased power, making your vehicle feel unresponsive.
5. Check Engine Light
Your check engine light may come on if your spark plugs are causing misfires or emissions issues. Our auto technicians can run a diagnostic to confirm the problem.
When Should Spark Plugs Be Replaced?
In general, most spark plugs should be replaced every 30,000 to 100,000 miles, depending on the type and your vehicle’s make and model. However, it’s best to consult your owner’s manual or check in with our team for a specific recommendation. Keeping up with regular maintenance at a reputable auto repair shop helps extend the life of your engine and improves overall performance. Come see us in Philadelphia, PA!
