The common sense of automobile maintenance is how to deal with the indirect vibration of automobile.

1. Throttling problem

The main reason of dirty throttle is carbon deposit at the joint between throttle valve plate shaft and throttle body, which leads to inaccurate throttle opening and idling jitter. You can clean the throttle. If it still shakes after cleaning, it may be that the throttle assembly is damaged and needs to be replaced.

2. Oil problem

Poor gasoline quality will lead to poor atomization effect of injector and insufficient combustion of mixed gas in cylinder, resulting in idling jitter. It is recommended to use high-grade gasoline, and do a fuel system cleaning after using this box of gasoline.

3. Spark plug problem

The spark plug does not ignite, which leads to one or more cylinders not working, and also leads to idle jitter. Check the ceramic part of the lower spark plug for cracks, and check whether the lower ignition module is normal.

Second, the vehicle shakes when accelerating.

The oil and spark plug problems mentioned above can also cause the vehicle to accelerate and shake while driving. In addition, the tire problem may also be a reason.

Tire problem

The uneven tread of four-wheel tires, such as bulging and foreign objects, will cause the vehicle to shake when driving. Of course, the looseness of wheel bearings will also cause the vehicle to shake when driving.

Third, the vehicle shakes when shifting gears.

1, transmission oil problem

Too dirty transmission oil will cause the vehicle to shake when shifting gears. You can check the transmission oil. If it turns black, it needs to be replaced. Generally, automatic transmission oil is changed once every two years or so.

2. The problem of the shift solenoid valve is automatic.

The failure of the shift solenoid valve of the gearbox will cause the vehicle to shake when shifting gears. You can use the tester to read whether the shift data of the gearbox is normal.
