What is the reason for the jerky shaking during sudden acceleration in the H6?
2 Answers
The reasons for the jerky shaking during sudden acceleration in the H6 are: 1. Excessive wear of the inner CV joint in the half-shaft; 2. Insufficient air, insufficient gasoline, and a well-functioning ignition system; 3. Aging spark plugs. The solutions for the jerky shaking during sudden acceleration in the H6 are: 1. Replace the half-shaft; 2. Ensure proper sealing of the ignition system and clear any blockages; 3. Replace the spark plugs. Taking the 2021 H6 as an example, it belongs to the compact SUV category, with body dimensions of: length 4615mm, width 1860mm, height 1720mm, wheelbase of 2680mm, fuel tank capacity of 58 liters, and a curb weight of 1675kg.
I totally understand the jerking sensation during sudden acceleration, as I've experienced it myself with older cars. The main cause is unstable engine output. For instance, worn spark plugs or excessive carbon buildup can lead to misfiring, causing a cylinder to stop working. If the ignition coil is faulty, the unstable current can result in shaking during acceleration. On the fuel side, clogged fuel injectors or low fuel pressure can cause insufficient fuel supply, making the car jerk. A dirty air filter can also disrupt airflow, leading to uneven combustion. Transmission issues might be another culprit—worn clutch plates in manual transmissions can slip, while torque converter failures in automatics can also cause shaking. I remember one time when my car shook badly, and after a quick repair with new spark plugs, it ran much smoother. Don’t ignore this issue—prolonged neglect can damage the engine and increase fuel consumption. Regular maintenance and checks on these components are recommended to ensure smooth and safe driving.
