What is the reason for the sudden change?

The most important reason for gear shifting frustration:

1. A large amount of gasoline carbon is deposited in the accelerator, injector, air intake and other parts of the car.

2. A lot of inferior oil was added when refueling. These fuels are of substandard quality and insufficient combustion, which will also cause the car to stumble.

3, the spark plug, ignition coil and other failures, so that it is frustrated.

4. There is an assembly problem with the clutch in the car.

5. The speed of the engine and the speed of the clutch plate are not synchronized, which may cause the impact when lifting the clutch.

Extended data:

In the process of shifting gears, when the clutch is in semi-linkage, it is necessary to stop for a while first, and then slowly lift the clutch, so that it can become much more stable during the whole driving process; When shifting gears, try not to lower the speed below 3500. After all, different engines will provide different power to vehicles, and only by maintaining the specified speed can we avoid relative frustration.

Sudden acceleration or acceleration after braking are the two situations that are most likely to cause frustration. The shift logic of the computer is judged and analyzed according to the driver's stepping on the accelerator. Under normal circumstances, when the driver refuels slowly, the original logic of the computer can accelerate only by upshifting. However, due to excessive force, the clutch found it necessary to downshift to complete this sudden acceleration intention during the upshift, and then downshift, so that the power could not be transmitted smoothly for a while and it was easy to cause frustration.
