What causes the entire body of the Tiguan to shake when accelerating from 60 to 90?

[LeMelanie]

The body shaking of the Tiguan when accelerating is mainly caused by the following two faults: 1. Excessive wear: Mostly due to excessive wear of the inner CV joint of the half-shaft. The change in the force point creates a certain angle between the transmission and the half-shaft, resulting in a jumping sensation in the vehicle. 2. Insufficient air or fuel: The engine requires sufficient air, sufficient fuel, and a well-functioning ignition system to operate properly. Any issue in these aspects can cause the engine to shake. 3. Quality issues: Ignition high-voltage wires rarely have problems, but ignition coils and spark plugs are consumable parts. When the performance of the spark plugs declines or inferior spark plugs are used, it can lead to weak acceleration and shaking during acceleration.
