Mercedes-Benz GLE trembles after 350 seconds.

The possible causes and solutions of jitter after Mercedes-Benz gle350 seconds are as follows:

1, engine cylinder shortage, engine cylinder shortage mainly refers to the abnormal operation of one or more cylinders of the engine, which is generally manifested as: the exhaust gas flow discharged by the automobile is obviously intermittent, the exhaust pipe is seriously shaken, and the engine jitter can be obviously felt, sometimes accompanied by sudden noise. This is mostly related to ignition coil failure. Solution: Replace the ignition coil.

2. The machine foot glue is aging or loose. Machine foot glue is a rubber block between the engine and the frame. Its function is to reduce the vibration and buffer when the engine works and fix the engine. Once these machine feet are aged or loose, the engine jitter will become extremely serious. The effect will be much weakened after changing the foot glue again.

3, ignition system problems, check the working conditions of spark plugs, high-voltage lines, ignition coils, the ignition system is not working well, and the spark plugs are not in good condition, which will also lead to this failure. Solution: Check whether there is too much carbon deposit in the spark plug and replace the spark plug.

4. The oil pressure is unstable. If the engine carbon deposit has been cleaned, the throttle valve has been cleaned, and the oil pad and spark plug have been replaced, it is still found that the car body is shaking at idle speed, which may be caused by the oil supply pressure and intake pressure sensors. If the oil supply pressure of the oil pump is abnormal, or the intake pressure sensor has an incorrect value and works poorly, it will lead to the body shaking. Solution: Check the oil pressure and replace parts if necessary.

5. The air filter is dirty. The air filter is designed to protect the engine from wear and tear, and it is usually replaced at about 10000 km. If it is not replaced in time, the engine will shake due to insufficient air intake, which can be solved by replacing the filter element.

6. The high-voltage line is broken, that is, the conductor core of the high-voltage line is broken, which will affect the ignition and cause the engine to shake. You can use a multimeter to measure the resistance, and change it to a resistance that is obviously several times larger.

7. The fuel nozzle is blocked. The fuel nozzle of EFI automobile is the key component of automobile fuel injection, and its service life is very long, reaching hundreds of thousands of kilometers. However, because there is gum in gasoline, it will block the injection hole of the nozzle, resulting in inconsistent injection quantity of each nozzle, inconsistent operation of each cylinder and engine jitter. The solution is to take it down and clean it.
