What Causes the Acceleration Resonance in Haval H9?
1 Answers
Haval H9 acceleration resonance is most likely caused by engine misfire. Excessive wear of the inner CV joint of the drive shaft: Due to changes in the force application point, a certain angle is formed between the transmission and the drive shaft, resulting in a jumping sensation in the vehicle. It is recommended to directly replace the drive shaft. Additionally, the main reason for excessive inner CV joint wear is often the failure to promptly replace the damaged dust cover on the drive shaft. Therefore, if the dust cover is found to be cracked and leaking oil, it must be replaced immediately to avoid greater losses. Air leakage or blockage: The engine requires sufficient air, adequate fuel, and a well-functioning ignition system to operate properly. Any issues in these areas can cause engine vibration. Minor air leaks or blockages may seem normal at idle, but during rapid acceleration, severe vehicle vibration and lack of power become apparent, and the engine warning light may also illuminate. Sealing any leaks or clearing blockages can resolve these issues. Damaged ignition coil or spark plugs: Ignition high-voltage wires rarely have issues, but the ignition coil and spark plugs are wear-prone components. If the spark plugs' performance declines or inferior quality spark plugs are used, it can lead to symptoms such as weak acceleration and shaking during acceleration.
