Tell-Tale Signs of the Need to See a Mechanic for Defective Spark Plugs

Posted on

Although visiting a mechanic is not something many motorists look forward to, these appointments are crucial for the overall performance of your car. Thus, it is unsurprising that you could be familiar with some of the symptoms indicating the failure of major components such as your transmission system, suspension and more so that you can seek repairs in good time. However, not all car problems point to the steady decline of a major system. Some of the most commonly overlooked issues occur when it is a seemingly minor component that needs to be replaced, as the motorist may not be familiar with the red flags to be wary of. Spark plugs, in particular, may be diminutive in size but are indispensable for the engine's performance. This article highlights a few tell-tale signs of the need to see a mechanic for defective spark plugs.

Your car keeps vibrating when coming to a stop

Slowing down to slide into a parking spot or as you approach the traffic lights should be smooth and easy. The moment that your vehicle starts vibrating spontaneously each time you are coming to a stop, it could be indicative of defective spark plugs that need to be replaced by your mechanic. When the spark plugs are compromised, they lose their ability to ignite the fuel and air in the combustion chamber efficiently. As a result, the mixture of air and fuel becomes imbalanced and this, in turn, will make your car shake, which is referred to as rough idling. It is worth noting that rough idling can also be caused by a variety of other automotive issues such as a damaged oxygen sensor, a faulty carburettor or even clogged fuel injectors. Nonetheless, it is advisable to visit a mechanic shop to establish if the spark plugs need replacing.

Your car is experiencing challenges with starting

As mentioned above, the spark plugs are responsible for igniting the air and fuel in the combustion chamber and this process ignites the engine. Therefore, when you begin to have trouble starting your vehicle, it could be indicative of the fact that the spark plugs have succumbed to corrosion. Old sparks that have acquired normal wear over the years will also lose their ability to ignite the air and fuel and this combustion chamber, which will lead to problems with starting your car. However, you should be cognizant that other auto parts such as the battery or even the alternator could cause issues with starting your car when they are defective. Thus, it is imperative to go to a mechanic shop to get to the root of the problem.
