MG 3 ran up and changed the ignition coil, spark plug and nozzle of the oil pump, which could not be solved.

The reasons for the deceleration of MG 3 may be high pressure fire failure, dirty throttle, insufficient oil pressure and blocked fuel injection head.

The gearbox is dirty;

In many cases, the damage is not the internal valve body, but the stubborn dirt and impurities inside the valve body, especially the dirt and impurities inside the valve body gather to form a blockage, which leads to the failure to effectively adjust the oil pressure and lead to the occurrence of bumping and slipping. At present, the traditional solution is to change the gearbox oil.

Throttle blockage:

In the intake system of the engine, the engine needs both air and oil. If the air filter, throttle and other parts are blocked or have problems, resulting in insufficient air intake, it will also cause the car to accelerate slowly and feel frustrated. The ignition system cannot be ignored. If the spark plug is poorly ignited, dripped or atomized, it will also affect the engine acceleration.
