Common Signs of Needing Spark Plug Replacement

Symptoms of Failing Spark Plugs

Spark plugs are critical components of an engine that generate electric sparks to ignite the fuel-air combination in the engine cylinders and generate energy. However, like all vehicle components, spark plugs have a limited lifespan, after which they become faulty and require replacement.

If you’re experiencing any of the following issues with your vehicle, contact the auto repair professionals at Bruno’s Automotive today to schedule a service appointment to have your car’s spark plugs inspected.

Continue reading below to learn more about some of the most common warning signs of defective spark plugs and when you should schedule a service appointment with an auto repair professional to have them replaced.

Engine Misfiring

An engine misfire causes the engine to halt for a brief moment before returning to regular operation and is especially noticeable when the car is accelerating or idle. Spark plugs that are failing can cause the car engine to misfire, lowering its performance. Furthermore, the failure of a single spark plug to ignite the fuel-air mixture might bring your engine to a standstill and potentially lead to incomplete combustion and damage to the car’s catalytic converter.

Car Won’t Start

If your car is having difficulty starting, it could be due to faulty spark plugs. Spark plugs that are worn out do not produce enough sparks to start the engine and fail to start the engine promptly. Furthermore, faulty spark plugs can also deplete the life of your car’s battery and interfere with the ignition system’s proper operation. If you notice this happening to your car, truck, or SUV, consider scheduling an inspection with a local auto repair shop to fix the problem.

Engine Knocking

Lastly, if your car’s spark plugs fail, your engine will occasionally make a pronounced banging sound, especially when accelerating. Luckily, this is a common occurrence with faulty spark plugs and is a quick and easy fix for an auto repair professional.
