1 1 Hyundai Elantra's engine noise during self-relieving acceleration and fuel collection: What is the reason?

Automobile engine noise is relatively large, which is generally caused by three reasons: 1, oil filter, air filter and air conditioner filter are not replaced for a long time, which is easy to cause the filter to be blocked by impurities, and in severe cases, it will send an error message to the engine control unit, resulting in damage to the engine and other components. 2. The engine produces carbon deposit, mainly because the gasoline is not fully absorbed by the engine, resulting in carbon deposit, which leads to insufficient combustion of the car, leading to car jitter and increased fuel consumption. 3. If the throttle or nozzle is not cleaned for a long time and the spark plug is not replaced for a long time, it will affect the fuel atomization combustion and lead to a series of problems.
