Is engine shaking related to gasoline?

[StMax]

Engine shaking is related to gasoline. Using lower-octane gasoline can cause knocking, which leads to engine shaking. It is recommended to remove the fuel tank and drain the gasoline. The causes of engine shaking include: 1. Low cylinder pressure—if one cylinder is not functioning properly, it can result in a misfire; 2. Carbon buildup and oil deposits clogging the throttle valve, idle valve, or intake ports over time, leading to poor airflow and unstable idling or shaking; 3. Clogged fuel injectors—the injectors in fuel-injected vehicles are critical components, and deposits in gasoline can block the injector nozzles, causing uneven fuel distribution among cylinders and resulting in engine shaking; 4. Abnormal coolant temperature; 5. Broken high-voltage wires; 6. Faulty spark plugs; 7. Dirty air filter.
