What are the causes of engine vibration in the Xiali N5?

[DeEverett]

The causes of engine vibration in the Xiali N5 include the following points: Aging spark plugs: Spark plugs are inherently wear-prone components and need to be replaced periodically according to the maintenance manual. However, most car owners do not strictly adhere to the replacement intervals specified in the maintenance manual unless the car exhibits problems. Aging ignition coils: Although ignition coils are not considered wear-prone parts and most vehicle models do not require regular maintenance or replacement, they are one of the components with a relatively high failure rate in the engine. The ignition coil's function is to supply high-voltage pulse current to the spark plugs, which is closely related to the ignition performance of the cylinders. This is also a common fault. Damaged carbon canister or carbon canister solenoid valve: Since the fuel vapor released by the carbon canister is a significant factor in the engine's air-fuel mixture, any blockage in the carbon canister or damage to the solenoid valve can disrupt the balance of the mixture, leading to engine vibration.
