As soon as the car stepped on the accelerator, the speed went up. Why can't it go up?

The oil pressure is not enough and the oil pump doesn't work well. The oil filter or nozzle is blocked.

At 3K per minute, the speed should be around 100, and the acceleration is weak. It is also possible that the clutch part is faulty (refueling or wear). Cold car may be better, but with the increase of temperature (driving), the probability of frequent occurrence is greater, or even "stop" driving (the film has been completely burned). ?

Throttle body, stuck or stepping motor failure (you wash it).

The exhaust part or contact with the catalyst may be blocked (you also washed it). It is also questionable. Materials, methods, and some cars have to be matched. ?

The wire is open or short-circuited, with poor conductivity. (such as ignition coil, spark plug, wire, etc. ).？

There is no real car, so there are other possibilities. It is recommended to go to after-sales maintenance. You only ran 23,000 kilometers, which is still under warranty.

Extended data:

Throttle, also known as "throttle" and "throttle". Refers to the control device that controls the engine power (thrust).

1, throttle, a device for controlling fuel supply on an internal combustion engine. The throttle of an automobile engine is generally controlled by a pedal, also called an accelerator pedal, which is a device for controlling fuel supply of an automobile engine.

2. The accelerator pedal is also called accelerator pedal. It is a part of automobile fuel supply system. By controlling the amount of pedaling, the throttle opening of the engine, the air intake and the oil quantity through the computer, the engine speed can be controlled.

3. The operation of the accelerator pedal should be based on stepping on the cab floor with the right heel as the fulcrum, lightly stepping on the accelerator pedal with the sole of the foot, and stepping down or relaxing with the extension and flexion of the ankle joint. When stepping on the accelerator pedal, the force should be gentle, so that you can step on it gently and lift it slowly.

Causes of abnormal sound of throttle valve:

1) Throttle is stuck due to carbon deposition, so clean the throttle;

2) The accelerator pedal support pin is worn. Adding butter can solve the problem. If it fails, replace it.

3) The throttle line is not installed correctly. If it is an electronic accelerator, please check the accelerator pedal mechanism and the accelerator pedal sensor.
