Willard abnormal noise, low speed, uphill engine abnormal noise?

Low-speed uphill engines rarely make abnormal noises, especially at the speed of 20-50. Sometimes there is no abnormal noise in the low-speed uphill engine, especially at the speed of 20-50. Sometimes without 1, the engine produces carbon deposits. This situation is mainly because the gasoline is not fully absorbed by the engine, which leads to the formation of carbon deposits and the combustion of the car. 2. If the throttle or nozzle is not cleaned for a long time, the spark plug is not replaced for a long time, or even the intake manifold fails, it will affect the fuel atomization combustion and lead to a series of problems. 3. If the oil filter, air filter and air conditioner filter are not replaced for a long time, it is easy to cause the filter to be blocked by impurities. In severe cases, it will send an error message to the engine control unit, resulting in damage to the engine and other components. It is still difficult to define the abnormal noise of your car Lang Wei and the rattle of the engine when going uphill at a low speed. I suggest you go back to 4S to check it out during the warranty period! This requires a professional master to check the engine through professional equipment! In addition, you can simply test it yourself. If your car is automatic, put it in manual mode, and then go uphill through low gear to see if there is such abnormal noise. If not, it should be related to the gearbox. The low-speed vibration and abnormal noise of Buick Lang Wei are mainly caused by three reasons: 1, and the engine produces carbon deposit. This situation is mainly due to the fact that gasoline is not fully absorbed by the engine, resulting in carbon deposition, which leads to insufficient combustion of the car, leading to vibration of the car and increased fuel consumption. 2. If the throttle or nozzle is not cleaned for a long time, the spark plug is not replaced for a long time, or even the intake manifold fails, it will affect the fuel atomization combustion and lead to a series of problems. 3. If the oil filter, air filter and air conditioner filter are not replaced for a long time, it is easy to cause the filter to be blocked by impurities. In severe cases, it will send an error message to the engine control unit, resulting in damage to the engine and other components. @20 19
