Clean the throttle and do not remove it.

Hello, landlord, have you finished cleaning the throttle and initialized it? If this happens after the throttle is initialized, something should be flowing back, but this situation will hardly happen.

So I suspect that the landlord did not initialize the throttle after cleaning. The throttle initialization is very simple. Open the key door to the second gear, the gear before ignition, so that the instrument panel is fully lit, then wait quietly for about 20 seconds, and then step on the accelerator to the end, 10 seconds or so. Throttle initialization complete! If not, then go to a professional garage and take off the battery 10 minutes. This is for the driving computer to learn memory again. If I don't do these two things, I can't help it.

I'm not a mechanic, but I've been driving for 15 years and I've encountered various failures. I have encountered this situation several times, and my father told me the above method. With these two methods, the fault you mentioned will be completely solved.
