What Causes Slight Idle Vibration in Baojun 310?

[AliyahAnn]

Baojun 310 slight idle vibration may be caused by the following reasons: Carbon Deposit Blockage: Severe engine carbon buildup is the most common cause of vehicle vibration, often due to dirty throttle valves or excessive carbon deposits in fuel injectors. When excessive carbon accumulates inside the engine, the gasoline sprayed by the cold-start injector is largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts and making ignition difficult. Poor Ignition System Performance: For ignition system issues, check the working condition of spark plugs, high-voltage wires, and ignition coils. Poor ignition system performance or inadequate spark plug firing can also lead to such symptoms. Unstable Fuel Pressure: If you have already cleaned the engine carbon deposits, throttle valve, replaced gaskets and spark plugs, but still observe idle vibration, it is recommended to visit a 4S shop to check the fuel supply pressure and intake pressure sensors. Abnormal fuel pump pressure or incorrect readings and poor performance of the intake pressure sensor can both cause vehicle vibration.
