The reasons for slight idle vibration in the new Magotan are as follows: Excessive carbon deposits: Severe carbon buildup in the engine cylinders can cause spark plug blockage and valve blockage, directly leading to vehicle vibration during idle. If the car's acceleration performance has significantly deteriorated and the vibration persists, an engine cylinder cleaning should be considered. Fuel supply system malfunction: Unstable fuel pressure can easily cause fluctuations in the concentration of the air-fuel mixture, not only resulting in vibration but also causing unstable idle. First, consider replacing the fuel filter, as prolonged use may lead to filter clogging. Then, check the fuel pressure bypassing the fuel filter. If abnormal, it may indicate a fuel pump issue. Aging engine mounts: Aging engine mounts are also a very common cause of vibration. If the engine vibration becomes increasingly severe but the power output does not weaken accordingly, it may be time to check the engine mounts.
