BYD's fifth gear speed is very slow. What happened?

There is something wrong with this car.

1, BYD Speed Sharp's engine nozzle is blocked, the oil pipe leaks, the power of the gasoline pump is reduced, and the gasoline filter is blocked.

2. The air filter and throttle are blocked.

3. The compressor has high power. All the above problems will lead to the slow speed increase of BYD.
