What is the reason why POLO suddenly shivers while driving?

POLO suddenly trembles when driving: The most common phenomenon of automobile engine tremors is due to serious carbon deposition in the engine, which is caused by dirty throttle or too much carbon deposition in the injector. It is recommended to clean the throttle and injector in 4s shop.

POLO suddenly trembled during driving for the following reasons:

1. If the throttle valve is too dirty and there is too much carbon deposit, the fuel injector will shake.

After driving for a certain mileage, the dirty throttle will cause the throttle to be closed loosely or the idle stepper motor to be stuck, which will lead to the excessive idle speed of the engine, and the carbon deposit generated when the engine works will also cause the vehicle to shake. Therefore, when the vehicle is shaking, first check the throttle and fuel injector. If the throttle valve is found to be too dirty or the fuel injector has too much carbon deposit, it should be cleaned in time.

2. Vibration caused by aging of engine rubber

Engine foot glue is actually the shock absorption system of the engine, which is responsible for absorbing the slight vibration when the engine is running.

3. Jitter caused by turning on electrical equipment.

With the opening of the electrical system, the engine will increase the load, leading to idling and slipping. In order to make up for the jitter caused by idling slip, the engine will automatically pull up the speed.

4. Vibration caused by uneven tire weight

If it is found that the tire weight is uneven, lead blocks need to be added inside the steel ring to make the tire weight on both sides uniform. Both steel rings and light aluminum rings will be deformed or broken when squeezed by external force. The deformation and uneven weight of the rim will also cause the shaking when driving, and the wrong angle of the rim will also cause the shaking when driving.
