What Causes the Car to Shake During Rapid Acceleration from a Standstill?
1 Answers
Possible causes include a dirty throttle body or excessive carbon buildup in the fuel injectors and intake manifold. Below is a detailed introduction regarding car shaking: 1. Causes of car shaking: Car shaking can occur during startup, idle, or high-speed driving. Shaking during startup is mainly due to insufficient fuel combustion, resulting in inadequate power output and low ignition energy. During startup, especially when fuel and lubricant temperatures are low, more throttle input is required to meet power demands. Additionally, the electrode gap of spark plugs gradually widens, leading to decreased ignition energy and poor fuel atomization. 2. Introduction to car shaking during idle: There are numerous reasons for car shaking during cold starts and warm starts. Apart from insufficient fuel combustion mentioned earlier, it could also be due to abnormal engine coolant temperature, low cylinder pressure, or clogged fuel injectors. If the car exhibits shaking during startup, it is recommended that the owner promptly take the vehicle to a 4S shop for inspection and repair.
