They are all 1.5 engines. Why is the rotating speed of Wuling Hong Guang high?

1, throttle assembly failure.

2, fuel pump and oil system.

3. Too much carbon storage.

4. The air-conditioning clutch slips or is damaged. Manual gearbox, power shift gearbox, semi-automatic gearbox and other forms of gearbox all use friction plate clutch to transmit engine power. If the torque is not enough or the friction plate is seriously worn, it will slip and lead to high speed.
