What Causes Slight Idle Vibration in Baojun 310?
3 Answers
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.
I've been driving for over a decade. The slight idle vibration of the Baojun 310 might be due to severe engine carbon deposits, especially carbon buildup on the intake valves and throttle body, which can disrupt airflow and cause unstable RPM. This is common in older vehicles or those frequently driven in congested urban areas. It's recommended to start with cleaning the throttle body, and regular use of fuel additives can help alleviate carbon deposit issues. Additionally, check if the spark plugs are aged or if the electrodes are worn, as ignition system failures can directly affect idle stability. Although slight vibration doesn't affect driving safety, long-term neglect can increase engine load. It's advisable to visit a 4S shop for a comprehensive diagnosis when you have time.
When I first bought the Baojun 310, I also encountered slight body shaking at idle, which was quite annoying. The mechanic said it was a common issue, possibly caused by worn spark plugs or faulty ignition coils. It could also be related to daily driving habits, such as aging engine mounts leading to increased vibration transmission. Later, I cleaned the throttle body and switched to high-quality engine oil, and the shaking basically disappeared. If the shaking becomes increasingly noticeable, it's best to get it checked promptly to avoid minor issues turning into major repairs.
