What is the cause of the engine shake of the MG3

Hello, there are many reasons for engine shake, such as unstable oil pressure, misfire, wrong engine timing, or dirty throttle, etc., it is recommended to use the computer to read the engine system fault to determine the scope of the fault.

Hello, this depends on whether it is idle shivering or accelerating start, if it is idle shivering, it is generally caused by the throttle being too dirty, if it is accelerating and shaking, it is generally caused by bad combustion.

If the engine shakes, it should be caused by too much carbon deposit in the engine, it is recommended to check the carbon deposit of the engine and clean the throttle.

Hello, serious shaking may be caused by the lack of cylinder in the engine, which needs to be checked or computerized, and the specific cylinder is not working well for specific maintenance, which may be caused by excessive spark plug clearance, ignition coil damage, fuel injector blockage, etc., it is recommended to go to the repair shop for inspection.

The engine shake of MG3 may be caused by carbon deposits, so it is recommended to clean the fuel injector and throttle valves, and replace the spark plugs.

Hello. Engine shake is generally related to carbon deposits, poor spark plug performance, ignition coil damage, low cylinder pressure, poor atomization of fuel injectors, air leakage in the air intake system, failure of a certain sensor, and low fuel pressure.

Engine shaking, check your throttle valve volume too much carbon, need to clean your throttle valve body, check your spark plug gap is too large, check your fuel injector atomization is not good.

Hello. For the shake of the engine, it is generally caused by internal carbon deposits, which can be overhauled by the repair shop, and if there is carbon deposits, it needs to be cleaned up in time.

Hello, the vehicle engine shake may be caused by the throttle is too dirty or the vehicle engine is missing, and you need to go to the repair shop to read the relevant fault code with the computer to determine the fault.

In this case, it is advisable to check the carbon deposition of the engine, which may be caused by excessive carbon deposition in the engine.

Engine shake is generally caused by excessive carbon deposits, it is recommended to clean the lower throttle to see the carbon deposits, replace the spark plugs, and look at the fuel injectors.

Hello, the engine shake phenomenon of MG3 should be caused by engine carbon deposits, you can clean the carbon deposits.

Hello, the engine of MG3 is shaking, most of which are caused by too much carbon deposits in the engine, which can be cleared.

Your situation should be caused by too much carbon deposition in the engine, it is recommended that you go to the 4S shop to clean the throttle valve and try the effect.

This situation is generally due to carbon deposition, you can go to the maintenance plant to clean the intake tract, clean the throttle, the cost is generally about 60 yuan.

If the shaking is slight, this is fine, but if the shaking is severe, it may be caused by carbon deposits in the engine.

Hello, if the engine is shaking, it may be due to too much carbon deposit, it is recommended to do a comprehensive cleaning.

Hello, this phenomenon you said should be caused by excessive carbon deposition on the throttle, and it is recommended to go to a repair shop to clean the throttle.

First of all, it is necessary to see if it is caused by excessive carbon deposition in the engine, clean the throttle and replace the spark plug.

Hello, it is recommended to go to the repair station to check whether it is caused by the lack of cylinder, read the fault code or data stream, and clean the throttle for test run.

If there is a slight shake after the engine starts, it should be normal, and if the shake is severe, it is recommended to clean the throttle.

Hello, first use the computer to check if there is a fault code, clean the throttle and try it. Change the spark plugs.

The engine shake of MG III is recommended to clean up the engine carbon deposits, which should be better.

If this is the case for you, it is best to clean the throttle injector and replace the better oil spark plugs.

If the engine shakes, generally speaking, do more wheel alignment, and listen to it for a few days to solve it.

The old MG or the new MG depends on what the shaking is.

MG 3 engine shake causes: First, oil quality problems. Second, the spark plug problem. Third, the problem of oil circuit blockage. Please check the above three questions, and your car will be fine.

As long as the car shakes while driving, everyone will say that the engine is shaking, and subconsciously feel that the problem is serious. In fact, shaking is inevitable when the engine is working, but under normal circumstances, the shaking of the car engine should be very smooth and regular. If you can clearly feel that the recent shaking of the car has increased or persisted, it is time to pay attention to maintenance.

Air is one of the power of the engine, if the air filter is not cleaned in time for a long time, the lack of air will cause the combustible mixture to be too thick, so that the engine power decreases; In the case of a vehicle with a turbocharger, a failure of the supercharger can also cause the engine to shake during acceleration.

If you can clearly feel that the recent shaking of the car has increased or persisted, it is time to pay attention to maintenance.

There are several types of jitter: high-speed jitter, idle jitter, and even jumping phenomenon occurs for individual car owners.

The argument for the phenomenon of engine shake is generally directly related to the following reasons, first of all, it is recommended that you check whether the carbon deposits at the throttle and idle valve are too much, and then if there is a problem with the ignition system, it will also lead to the above phenomenon, given that you have replaced the spark plug and high-voltage wire, then you also need to check whether the ignition coil is working normally, and then if the fuel pressure is insufficient or the fuel injector is caused by dripping or blockage.

In autumn, it is proved that he has been proud of his strength, and in spring, he sows good seeds; Summer, hard work. Finally, to get the happiness of the harvest, the autumn night Wu Fangzhen, in the dark night, the fifteenth moon is like a silver plate full of crystals, shining and attractive. The little stars that shine in the thick and shining cavity are the crystals that flash in the silver plate, and in the golden autumn, the withered yellow leaves dance in the air, and the days are long, the leaves rot, and the fertile land is fully prepared for the germination of seeds next year.

Air filter dirty:

The air filter is designed to protect the engine and reduce wear, generally replaced in about 10,000 kilometers of imitation rock, if the replacement is not timely, it will cause low idle speed caused by insufficient air intake, and the engine shakes, as long as the filter element is replaced.

High-voltage line break: High-voltage line break refers to the high-voltage wire core break, which can affect the ignition and cause the engine to shake.

Spark plug life:

Spark plugs have a lifespan of more than 3-

After 40,000 kilometers, the ignition efficiency is significantly reduced, and the ignition can be affected, which is the most common failure, and the spark plug can be replaced completely.

Low idle speed: The engine idle speed value has been set in the computer, and when the number of revolutions is low to a certain range, the car computer will automatically adjust it. If the idle speed is too low and the jitter is beyond the control range of the computer, some cars have adjusting screws on the throttle to adjust the idle speed, and some cars can not adjust, this kind of car can check the idle valve, throttle, air flow meter, vacuum sensor, adjust the ignition time (car with distributor), you can increase the idle speed.

Low idle speed can occur even when the water temperature is low, so you can check and replace the thermostat.

The water temperature is not normal:

There is a normal range of engine operating temperatures, and high water temperatures will cause earlier ignition times, changes in the oil-air mixing ratio, thinner oil viscosity, and worse lubrication performance. The general cause of the fault is the lack of antifreeze, the thermostat can not be opened, the fan does not rotate, and the temperature of the temperature control switch is inaccurate.

Fuel injector clogged:

The fuel injector of the EFI truck is a key headroom component for automobile fuel injection, and the service life is very long, which can reach hundreds of thousands of kilometers. However, because there is gum in the gasoline, the fuel injection hole of the fuel injector will be blocked, so the amount of fuel injected by each fuel injector is inconsistent, resulting in the inconsistent work of each cylinder and causing the engine to shake. The solution is to remove it and clean it.

Carbon deposits, grease blockages:

The throttle, idle valve, and air intake hole will be blocked by carbon deposits, oil scale, and poor air intake after a period of use, which will affect the stable idle speed and shaking. It is necessary to inspect and clean the above parts with cleaning agent, and there is no need to remove them for cleaning.

Low cylinder pressure: The engine has 3 cylinders, 4 cylinders, 5 cylinders, 6 cylinders, and 8 cylinders. Three-cylinder engines are the most obvious, followed by four-cylinders.

Check the cylinder pressure with the cylinder pressure gauge, and solve the fault of low pressure with Xinba. Xinba has a unique effect on low cylinder pressure and unbalance. It can be added to the engine oil or directly added to the cylinder to restore the balance cylinder pressure.

Hello! Regarding the question you asked, this fault is obviously a problem with the idle speed control. The idle control system of the electronically controlled engine is mainly composed of various sensors, signal control switches, electronic controllers and idle control valves.

The ECU controls the engine to maintain optimal working condition based on the input signals from each sensor. When the load on the engine increases, such as when the electronic fan is working or the air conditioning system is activated, the ECU will collect the signals from each sensor and achieve fast idle speed to ensure that the engine speed is stable. After this kind of failure, it is important to check whether the input signal from each sensor to the ECU is normal, and then check the working condition of the actuator.

All in all, for such faults that are not easy to find, it is necessary to use a diagnostic computer to make judgments, and it is necessary to measure each line patiently. It is recommended that you go to the 4S store for on-site inspection according to the above conditions.
