The fourth and fifth gears of the second-generation Geely King Kong have regressed. What's with the slow and urgent speed?

Let me answer this question and solve the problem on the vehicle for you.

First of all, as soon as the car shrugs, it is necessary to find problems from several aspects. This question will be more common if you are a novice. It's not the car. It is caused by releasing the clutch too quickly. As soon as the car shrugs, it will be fine after a long time. You know when to release the clutch and shift gears.

If the speed is abnormal, especially when the car is driving, it feels that the fuel is out of reach and the tachometer is also very high. This is necessary to check your throttle. Generally, there is too much carbon on the throttle of a manual transmission car, which will cause the situation that the fuel cannot be supplied, and the problem of cleaning the throttle will be solved.

There is no abnormal noise in the clutch, and there is no problem stepping on the clutch when it is in gear. This is your car. There is too much carbon in the throttle. Clean the throttle and give the car a bottle.

To sum up, the subject's car is caused by too much carbon deposition on the throttle, and cleaning the throttle can solve the problem.
