What Causes Engine Shaking After Cylinder Head Assembly Replacement?

[DiFelicity]

The causes of car accelerator pedal shaking include engine misfire, dirty engine throttle, and aging rubber components inside the mounts. Below are the specific reasons for car accelerator pedal shaking: Engine Misfire: This may be due to an engine misfire fault, causing one or more cylinders to stop working, resulting in severe engine shaking transmitted to the accelerator pedal. Common fault points for misfires include: faulty spark plugs, malfunctioning ignition modules, or poor fuel quality. Dirty Engine Throttle: It could be caused by a dirty engine throttle, leading to engine shaking. It is recommended to inspect the throttle and clean it if excessively dirty. Aging Rubber Components Inside Mounts: The shaking may be due to aging rubber components inside the engine and transmission mounts, which can no longer absorb the vibrations generated during engine operation, causing the shaking to be transmitted to the accelerator pedal.
