Spark plugs are responsible for igniting the air-fuel mixture in your engine's cylinders. If the spark plugs are not working properly, the mixture will not ignite properly, which can cause the engine to misfire. Misfires can cause the engine to抖动or vibrate.
In addition, bad spark plugs can also cause the engine to run rough, idle erratically, and have reduced power. If you are experiencing any of these symptoms, it is important to have your spark plugs checked and replaced if necessary.
