What are the reasons for the idle engine vibration in Changan Raeton CC?
2 Answers
The following are the reasons for the idle engine vibration in Changan Raeton CC:1. Sensor failure: It may be due to signal confusion from sensors such as the air flow sensor or fuel consumption sensor in the engine, leading to deviations in the computer's reception and causing the engine to vibrate at idle.2. Insufficient oil supply: It might be because the engine oil did not keep up in time during operation, preventing the engine from obtaining optimal mechanical operating conditions, resulting in engine vibration.3. Computer board issue: There could be inherent problems with the vehicle's computer board, which is also a reason for the engine's idle vibration. The onboard computer receives incorrect signals from the engine or sends out chaotic signals, leading to engine issues.
I've been driving this car for years, and the Changan Raeton CC's engine shakes at idle. The most likely causes are from the ignition system or fuel system, such as aging spark plugs causing unstable ignition, or clogged fuel injectors leading to uneven fuel atomization. Excessive engine carbon buildup can also cause this, as deposits on the cylinder walls affect power balance. Sometimes, a dirty throttle body results in inaccurate air flow at idle, making the engine struggle. I suggest first checking the spark plugs yourself. If the shaking persists after replacing them, check if the fuel pump pressure is normal. Poor fuel quality can worsen carbon deposits. Quickly take it to a 4S shop for diagnostics to avoid prolonged wear on other components. Idle shaking isn't just annoying—it also affects fuel consumption and emissions. Fixing it early ensures peace of mind on the road.
