1.Engine Fault Light OnWhen the engine fault light is on, it indicates that the engine control system has detected an anomaly. This can be caused by aging or damaged spark plugs, or faulty ignition coils. At this point, you need to check the spark plug and ignition system as soon as possible, and replace the damaged parts in time. If this problem is ignored, it can lead to more serious engine failure or even the need for a major overhaul.
2.Engine ShakeIf the engine is shaking, it can be caused by aging or damage to the spark plug. When the spark plug fails to ignite properly, it will cause the mixture to burn inadequately, resulting in a large amount of carbon deposits, which in turn will cause the engine to shake. At this point, you need to check the condition of the spark plug and replace the damaged parts in time. If the jitter problem is severe, other parts of the engine, such as valves, pistons, etc., also need to be checked.
3.Slow AccelerationIf you feel that your car is accelerating slowly, it may be due to aging or damage to the spark plugs. When the spark plug cannot be ignited properly, it will lead to insufficient combustion of the mixture, which will affect the power output of the engine. At this point, you need to check the condition of the spark plug and replace the damaged parts in time. At the same time, the engine's fuel system and air intake system need to be checked to ensure that they are working properly.
4.Increased fuel consumptionIf your car's fuel consumption suddenly increases, it may be caused by aging or damaged spark plugs. When the spark plug fails to ignite properly, it will cause the mixture to burn inadequately, which in turn will affect the fuel economy. At this point, you need to check the condition of the spark plug and replace the damaged parts in time. At the same time, other components such as the car's tires, brakes, and drivetrain need to be inspected to ensure that they are working properly.
