What are the causes of automobile steering wheel jitter?

Many car owners must feel the steering wheel shaking when driving or parking. Let's take a look at some reasons for steering wheel jitter.

1, carbon deposition leads to unstable idle speed.

Excessive carbon deposition will lead to unstable idle speed of the engine, and the positions of throttle and nozzle are more common. When the carbon deposit is serious, the gasoline adsorbed on the carbon deposit after starting the vehicle will be sucked into the cylinder for combustion by the vacuum suction of the engine, which will increase the concentration of the mixed gas and make the mixed gas in the engine thin and thick, which is easy to cause idling jitter.

In addition, the air inlet is blocked, which will also lead to the same problem.

2. When the vehicle speed is 30 to 40 kilometers per hour, the vehicle body has a sense of shaking.

How to solve it: This situation is mostly caused by tire deformation caused by friction, bumping or aging in daily use, and it is possible to replace the tire.

3, ignition system failure

This is also an important reason for the body jitter at idle speed. If there is something wrong with the spark plug, high-voltage wire and ignition coil, the body of the starting car will shake. At this time, you can check whether there is too much carbon in the spark plug, and replace it with a new spark plug if necessary.

4. The machine pad is damaged

The machine pad is added to prevent the engine from high-speed vibration! Once the machine foot pad is damaged, there will be great vibration between the engine and the frame, and the body will shake and make abnormal noise!

Solution: Replace the machine foot pad.

5, oil pressure instability caused by jitter

If the air pressure sensor value is inaccurate after the oil pump oil supply pressure is abnormal, it will also shake. You can check the oil pressure at this time. If it needs to be replaced, it should be replaced in time.
