What Causes Body Trembling During Acceleration in Volkswagen Tiguan?

[NicoleRose]

The causes of body trembling during acceleration in Volkswagen Tiguan are as follows: 1. Excessive carbon deposits: Severe carbon buildup in the engine cylinders can lead to clogged spark plugs and valves, directly causing the car to shake at idle. If the vehicle's acceleration performance has significantly declined and the shaking is persistent, consider an engine cylinder cleaning. 2. Fuel supply system malfunction: Unstable fuel pressure can cause inconsistent mixture concentration, resulting not only in shaking but also unstable idle. First, consider replacing the fuel filter, as prolonged use may clog the filter element. Then, check the fuel pressure bypassing the fuel filter; if abnormal, the issue might be with the fuel pump. 3. Worn engine mounts: This is a very common cause of shaking. If the engine shaking worsens over time but the power output does not weaken accordingly, it may be due to faulty engine mounts. 4. Misfiring cylinders: This is the most common cause of engine shaking, if not the only one. The problem lies with the engine ignition coils or spark plugs. If the ignition coils malfunction or the spark plugs fail to fire for some reason, the car will experience shaking.
