What Are the Reasons for Steering Wheel Vibration After Wheel Balancing?

[DeVincent]

The reasons for steering wheel vibration after wheel balancing include excessive engine carbon deposits, ignition system failure, and unstable oil pressure. The specific explanations are as follows: Excessive Engine Carbon Deposits: Dirty throttle valves or excessive carbon deposits on fuel injectors are the most likely causes of car vibration. When starting the car, fuel on the carbon deposits is sucked into the engine cylinders for combustion. Due to the fluctuating amount of combustible gas mixture in the engine, the car body may vibrate during cold starts. Regular cleaning of the throttle valve and other fuel system components can prevent this issue. Ignition System Failure: This is another major cause of car body vibration at idle. If there are issues with spark plugs, high-voltage wires, or ignition coils, the car body may vibrate when starting. It is advisable to check if the spark plugs have excessive carbon deposits and replace them if necessary. Unstable Oil Pressure: If the oil pump's fuel supply pressure is abnormal or the intake pressure sensor readings are inaccurate, vibration may occur. In such cases, checking the oil pressure is recommended, and timely replacement of components is necessary if required.
