What should I do if the car engine shakes? Teach you a few tricks to solve it easily

In the old society, few families could own cars. At that time, drivers were basically half mechanics, but with these two years, cars have become more and more popular. Most people don't know much about cars, they can only drive. But if it needs to be repaired, many people still don't understand. If there is something wrong with the car, you can only go to some repair shops or 4s shops, but the price will be high. So today Bian Xiao will share with you what is the cause of car jitter!

In the second case, when the vehicle is driving, where will the body shake?

The first reason may be tire deformation or imbalance. Drivers and friends are advised to check the tires as soon as possible and do a good job of four-wheel balance. If the vehicle is still accompanied by some deviation at this time, it is necessary to do four-wheel positioning.

In fact, the second reason may also be that the gearbox shaft is unbalanced due to deformation. It may also be some problems caused by the damage of constant velocity universal joint. In fact, under normal circumstances, vehicles with older chassis will have such problems after being hit, and this possibility is also relatively large.

The second case is that the body will shake when idling.

This kind of problem should be the most common fault phenomenon encountered by car owners. There are four reasons for this idling jitter. The first is the serious carbon deposition in the engine. If the engine has too much carbon deposit, when the cold car system is started, the gasoline in the fuel injector will be absorbed by a large amount of carbon deposit, resulting in insufficient fuel entering the cylinder, which leads to the overdue of the mixer and the difficulty in starting the cold car. At this time, it is necessary to clean up the carbon deposits in the intake branch pipe and throttle valve.

The second reason may also be caused by the aging of engine pads, mainly because some old models account for a large proportion. Because the foot pad of the engine is actually the shock absorption system of the engine. It is also responsible for filtering some slight jitter generated when the engine is running at high speed. If the machine pad is aging. The vibration of the motive will be transmitted to the whole body, and the body will shake when the vehicle is idling. Just check the engine pedal and replace it in time.

The third reason is that the ignition system has failed. This part is an important part of the engine. If the ignition system fails, the whole engine will not work. It can also cause jitter. In severe cases, the car body will tremble like a pendulum, and it will be accompanied by insufficient power and increased fuel consumption. Reading this fault code with the detection computer can determine which cylinder has a problem, and replace the spark plug, high-voltage line or ignition ring. It may also be a fault caused by unstable oil pressure. When your vehicle has cleaned the engine carbon deposit and ignition system, the body shake will still occur when idling. The pressure in the fuel system may be abnormal. At this time, it is necessary to measure whether the fuel pressure is in a normal state, and it can be solved after cleaning the fuel nozzle.

All the above are common causes of body shake caused by engine, if your car has these faults. You can check according to these methods.
