What are the reasons for severe engine shaking in Chery A5?

[Wendy]

Severe engine shaking in Chery A5 may be caused by issues such as engine misfire or engine mount problems. Reasons for car engine shaking: Dirty air filter: If the air filter is not replaced in time, insufficient air intake can lead to low idle speed, causing the engine to shake. Low spark plug efficiency: Affects ignition, making it difficult to start. Abnormal water temperature: High engine water temperature can cause early ignition timing, changes in air-fuel mixture, thinning of oil viscosity, and poor lubrication performance. Common causes include lack of antifreeze, thermostat failure, non-functioning fan, or inaccurate temperature control switch. Methods to address engine shaking: Replace spark plugs: Spark plugs have a lifespan, and their ignition efficiency significantly decreases after 30,000 to 40,000 kilometers, affecting ignition. Adjust water temperature: High engine water temperature can lead to early ignition timing, changes in air-fuel mixture, thinning of oil viscosity, and poor lubrication performance.
