How does Conray H3 sway at a speed of 30-40 miles per hour?

Car jitter is caused by wheels, engines, oil supply systems, etc.

1, it may be that there is something wrong with the wheel dynamic balance, or it may be that the car shakes due to the * * * vibration. It is recommended that the owner go to the 4s shop for maintenance.

2. Serious carbon deposition in the engine will lead to dirty throttle or carbon deposition in the fuel nozzle, and the fuel in the combustion chamber cannot be completely burned, which will affect the power transmission and cause the car to shake.

3. Tires are deformed due to friction, bumping or aging in daily use.

4. Oil supply system failure. Unstable oil pressure will easily lead to unstable mixture concentration, which will not only cause jitter, but also cause unstable idle speed.

5. Lack of cylinder and misfire This is a common cause of engine jitter. The problem lies in the engine ignition coil or spark plug. If there is something wrong with the ignition coil or the spark plug fails to catch fire for some reason, then the car will shake.
