Signs You Have Faulty Spark Plugs

A spark plug is one of the most underrated car components. They play a crucial role in igniting the air-fuel mixture within the engine cylinders to get and keep your vehicle moving. With time, your spark plugs might become fouled and dirty, impacting your engine performance. When a spark plug is fouled, it is usually covered with such substances as fuel, carbon, or air. At this point, the only way you can enhance your engine performance is by having your spark plugs cleaned without causing any damage to the electrodes.


Most manufacturers will recommend that you have your vehicle's spark plugs replaced every 30,000 - 50,000 miles. If you haven't had yours checked in quite some time, you might want to consider contacting our mechanics now.


Here are some of the signs that your spark plug is failing and needs a replacement:


Reduced Gas Mileage


If you find yourself making trips to the gas station a little too much than usual, you might want to check out your spark plugs. Fouled and dirty spark plugs can take a significant toll on your vehicle's fuel economy.

Trouble Accelerating

Most acceleration troubles in your vehicle are associated with a failing ignition system. While the problem could also be with a failing sensor or a fuel filter, sometimes it might result from a worn-out spark plug. If your vehicle is a little sluggish, unresponsive, and takes longer to accelerate, have our ASE-certified mechanics check and address this problem to get things to speed up again.


Engine Misfires


Engine misfires in modern cars are mostly associated with malfunctioning sensors. Even so, it could be a result of a broken spark plug. You might notice your engine hesitating, occasionally jerking up or making sputtering noises. Driving your car in such a state will decrease your vehicle's fuel economy, engine power and offer you a rough, uncomfortable ride.
