What Causes Acceleration Shaking?

[DeStella]

Acceleration shaking is caused by excessive carbon buildup in the throttle body, intake tract, and valve areas, which leads to an overly rich air-fuel mixture during engine idling, resulting in unstable idle. Solutions for acceleration shaking: 1. Severe carbon buildup in the engine or idle control valve - clean the fuel system; 2. Ignition system issues - check if spark plugs have excessive carbon buildup and replace them if necessary; 3. Unstable fuel pressure - inspect fuel pressure and replace corresponding components; 4. Aging engine components - replace worn parts. Functions of the engine: 1. Fully burn the fuel introduced into the cylinders to generate power; 2. Determine the vehicle's power performance, fuel economy, stability, and environmental friendliness.
