The sound of the car stepping on the accelerator is loud, but the speed can't go up and the speed can't be explained.

1, 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).

2. The throttle body is stuck or the stepping motor is faulty (you washed 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.

3. The circuit is open or short-circuited, resulting in poor conduction. (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.
