What Causes the Buzzing Resonance When Pressing the Throttle at Low Speed?
1 Answers
Reasons for buzzing resonance when pressing the throttle at low speed: 1. The engine oil has not fully lubricated all components of the engine. It takes some time for new oil to evenly lubricate all parts of the engine. 2. It could be due to severe wear, leading to poor filtration (most commonly caused by a dirty air filter). 3. Large gaps or poor sealing can worsen the engine's condition and may also cause noise. It is recommended to visit a repair shop for inspection. Methods for cleaning the engine fuel system: 1. Add the "cleaning agent" directly to the fuel tank in a certain proportion and perform an internal circulation cleaning while the car is running normally. 2. Use specialized equipment to clean the engine while it is idling, ultimately expelling the decomposed carbon deposits along with the exhaust gases.
