Is Car Shaking Related to Gasoline?

[StMakayla]

Engine shaking is related to gasoline. Using low-octane gasoline can cause knocking, which leads to engine shaking. It is recommended to remove the fuel tank and empty the gasoline. The causes of engine shaking are as follows: 1. Low cylinder pressure: If one cylinder is not functioning properly, it can cause misfiring and engine shaking. This is most noticeable in three-cylinder engines, followed by four-cylinder engines. Use a cylinder pressure gauge to check the cylinder pressure and resolve low-pressure issues with Xinba. 2. Carbon deposits and oil sludge blockage: Over time, the throttle body, idle valve, and intake ports can accumulate carbon deposits and oil sludge, leading to restricted airflow and unstable idling, resulting in shaking. 3. Clogged fuel injectors: The fuel injectors in electronic fuel injection vehicles are critical components for fuel delivery and have a long lifespan, often lasting hundreds of thousands of kilometers. However, gum deposits in gasoline can clog the injector nozzles, causing uneven fuel delivery among cylinders and leading to engine shaking. 4. Abnormal coolant temperature: Common causes include insufficient coolant, a stuck thermostat, a non-functioning fan, or inaccurate temperature control switch readings, all of which can cause shaking. Resolving these issues will eliminate the shaking. 5. High-tension wire breakage: A break in the high-tension wire core can affect ignition and cause engine shaking. Use a multimeter to measure resistance and replace any wire with significantly higher resistance.
