Spark plugs are an integral part of a well-maintained engine, and it is essential that they have clean contact surfaces and unbroken electrodes. If the spark plugs in an engine are dirty or fouled, the engine's performance may get diminished. A faulty or fouled spark plug is one that is encrusted with oil, gasoline, or carbon or that has blistered from overheating. You risk serious harm to your engine if you drive a vehicle with worn or fouled spark plugs.
Here are 5 signs that your spark plugs are worn out or fouled and need to be changed as soon as possible by a qualified mechanic. The next time your spark plugs need to be replaced, give A Plus Automotive a call.
Reduced Gas Mileage
A properly working spark plug is essential for a clean and efficient combustion cycle. If this happens, your automobile will get greater gas mileage than usual. Too little or too much space between the spark plug electrodes is usually to blame when the plug is not performing as it should. Spark plug wear is a frequent contributor to decreased fuel economy.
Slow Acceleration
The ignition system is usually to blame when acceleration is subpar. In today's vehicles, the spark plug is ignited by an electronic pulse sent from the engine's control module. It's possible that the sensor is at fault in certain cars. Wear and tear on the spark plug's igniting element will drastically lessen the plug's capacity to generate a spark. As a result, this changes the rate at which the car accelerates.
Hard to Start
If it's becoming harder to start your car, the spark plugs may be worn out. Cars are more difficult to start when their spark plugs cannot produce a spark that will last long enough to ignite the fuel and air mixture. When you first notice difficulties starting your car, it's best to have a professional take a look.
Engine Misfires
Problems with the ignition system generally cause misfires in an engine. In a modern car, this is often caused by a malfunctioning sensor. It's also possible that the spark plug wires or the connections between them are faulty. Misfires in an engine manifest as stuttering or stumbling noises that occur periodically. A misfire is a clear indication that there is a problem with the engine. If the engine keeps misfiring, it will produce more harmful pollutants, have less power, and use more gas.
Rough Idling
If your engine is making a jerky idling sound, you may need to replace the spark plug. Your car will rattle from the engulfing trembling sound. If the misfire occurs solely at idle, it may be a sign of a faulty spark plug.
