What causes the car body to shake after ignition?
1 Answers
Engine shaking after startup may be caused by aging engine mounts, excessive carbon buildup in the throttle body, or poor operation of a certain cylinder. Here is relevant information: 1. Material aspect: Engine mounts are typically made of rubber. Rubber products will age over time, and when rubber mounts harden with age, it can cause some vibration during engine operation. 2. Importance aspect: The throttle body is known as the engine's throat. When the accelerator pedal is pressed, the throttle opening increases, allowing more air into the cylinders, and the ECU then controls the fuel injection system to increase fuel delivery. If there's carbon buildup on the throttle body, it may cause unstable engine idle.
