What are the reasons for slight engine vibration in Jetta?

Jetta engine slight vibration may be due to severe engine carbon deposits, it is recommended to go to the garage for cleaning. Other reasons for engine vibration: Severe engine carbon deposits, a very common cause of car vibration is dirty throttle or excessive carbon deposits in the fuel injector. When there is too much carbon deposit inside the engine, the gasoline sprayed by the cold start injector will be largely absorbed by the carbon deposits; timely cleaning of carbon deposits is required; engine misfire: engine misfire mainly refers to one or more cylinders of the engine not working properly, manifested as: the exhaust gas flow from the car has obvious intermittence, at the same time the exhaust pipe vibrates violently, and the engine vibration can be clearly felt. The combustible mixture in the engine is sometimes lean and sometimes rich. The role of the engine: The car engine is the device that provides power for the car, it is the heart of the car, and is an energy conversion device. Its function is to convert the heat energy of gasoline (diesel) into mechanical energy by burning and expanding the gas in the sealed cylinder to push the piston to do work. According to different power sources, car engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrid power, etc.
The engine is shaking a bit, which might be related to the ignition system. Over time, spark plugs can age or become covered with carbon deposits, leading to poor ignition and unstable cylinder operation, causing the entire engine to vibrate. I've encountered this situation before, and replacing a set of new spark plugs can significantly reduce the shaking. If the ignition coil is faulty, it can also cause this issue, especially after prolonged driving or in humid weather conditions. Regular inspection and replacement of these small components are crucial to avoid bigger problems and higher costs later on. During regular maintenance, it's important to avoid using low-quality gasoline, as it can accumulate and damage the spark plugs. Engine shaking not only makes driving uncomfortable but can also harm the engine. Addressing it early is better for the car.
