Is the abnormal sound of Geely Emgrand gs gearbox related to the throttle?

The abnormal sound of Geely Emgrand gs gearbox is related to the throttle. The performance is that when refueling at a low speed, the car will shake and make an abnormal noise. Gearbox jitter is usually caused by excessive carbon deposition in the throttle, unclean air filter, spark plug failure, aging of internal components of the engine and other reasons.

Engine dust accumulation

If the engine is caused by too much carbon deposit, then the carbon deposit will suck some oil when starting, resulting in a low mixture. When carbon deposits absorb gasoline, the engine will start, the mixture will be ignited, and the carbon deposits with gasoline will be sucked into the cylinder, causing the engine to shake violently. If the spark plug fault causes the engine to shake, it is mainly because the ignition coil or spark plug can't jump, which leads to the lack of cylinder in the engine, and the car will shake violently at low and medium speeds.

If the throttle valve or air conditioning filter element is too dirty, the throttle valve will not be closed tightly, or not enough air will enter the cylinder, which will affect the mixture, and eventually lead to insufficient engine power and jitter. If it is because the engine parts are aging, it is necessary to check the specific location of the fault.
