What if Ruifeng m5 1.9t Expressway can't be accelerated?

Lack of motivation mainly has the following possibilities:

transfer system

Is there too much resistance in the transmission system? For example, the handbrake is not released and the brake is stuck. Check whether the car is running off and the wheels are overheated. Or ask the master to slide on the flat road to see if the distance is too short.

oil supply system

It is possible that the oil is too thick or too thin. See if the exhaust gas has color and the water temperature is high. Black smoke is too thick, blue smoke is oil leakage, and white smoke or too much water is cylinder gasket.

Gas supply system

The airway is blocked, but it cannot be maintained normally. Check whether the air filter is dirty, whether the throttle valve is greasy, and whether the vacuum tube falls.

circuit

Generally, it won't break, and it won't come out until it's torn down.
