________________________________

Have you ever wondered how often you should change your car's spark plugs? Leachman Buick GMC located at Scottsville Road, Bowling Green, KY has an excellent service center with certified technicians ready to help you with your regular maintenance and unexpected repairs.

Your car's ignition system is in charge of providing each cylinder with a correctly timed spark to aid combustion. Your vehicle's spark plugs are one of the most important ignition components, and they must be changed as part of routine maintenance, sometimes known as a tune-up.

This, of course, raises the question about when spark plugs should be replaced.

The basic answer to the topic about how often to replace spark plugs is as often as the manufacturer recommends. The mileage between such services might vary a lot from one manufacturer to another, as well as between various types of spark plugs. The most frequent mileage periods, however, are around 30,000 miles. Always reference your vehicle's owner's handbook for accurate replacement interval guidelines. Although spark plug replacement is generally dictated by intervals of this sort, it is not the only time when it is required. When a mechanical fault with one or more plugs is discovered, spark plug replacement may be necessary. But how can one recognize when such a problem has arisen?

Whenever a spark plug fails to ignite as it should, numerous consequences on the vehicle's performance might occur, necessitating the installation of new plugs. The degree of these problems is frequently defined by the kind of spark plug malfunction that occurred and the fundamental cause of that failure.

Whenever a spark plug malfunctions, the cylinder to which it is assigned does not burn properly, resulting in a misfire. In most situations, this results in an unevenness that can be felt when idling, as well as when driving. This is often the first sign that there may be a problem with your car.

The check engine light is frequently activated when a spark plug fails. This causes your car's computer's capacity to identify and track engine misfires. The engine's operation computer detects the malfunction and illuminates the engine light to alert you to the problem since a poorly functioning engine can cause both driving difficulties and an elevation in hazardous emissions.

Performance diminishes when an engine is forced to run without all its cylinders contributing equally. Poor acceleration and throttle response can cause an engine that was previously robust to suddenly become weak.

Fuel cannot be burned efficiently when there is insufficient spark in any of your engine's combustion chambers. As a result, excessive fuel consumption and low overall fuel efficiency result. Trips to the gas station might become more frequent in a shorter period. Before determining that your spark plugs are the source of any of the above-mentioned problems, it is frequently essential to rule out other concerns, such as a malfunctioning ignition coil, as the underlying cause. Your mechanic may also examine your spark plugs for indications of carbon clogging, gasoline saturation, or an out-of-line gap. The technician will remove them and examine them. If necessary, they will be replaced as you cannot generally repair spark plugs. Installing new spark plugs is often required only after your vehicle has reached the factory-recommended service period or when your car's engine is running badly, and bad spark plugs are the suspected culprit.

You'll never have to wonder if it's time to change your car's spark plugs again if you use your car's manuals and pay close attention to the status of your engine's performance. If you notice the check engine light is on, the car is idling rough while sitting at a red light or driving, you’re getting poor gas mileage, the vehicle is misfiring for no apparent reason, or it is simply not running right.

If you bring your car to the dealership for regular maintenance service as suggested and/or scheduled, and if you notice any issues with your vehicle and bring it in, you shouldn’t have very many problems with your car. Just don’t miss your scheduled maintenance appointments and your car should run well for a long time.
