The accelerator of the new Jetta is dirty. Can you clean it with fire?

You mean cleaning with the engine running, right? This is not good. As for the principle, I don't know clearly. Try to guess: the function of the throttle valve is to inhale air and burn it after mixing with gasoline. If the engine is not turned off for cleaning, the throttle will suck in air and cleaning liquid, and then mix it with gasoline. I don't know if it can burn normally. I haven't done this anyway.

Normal cleaning is carried out when the car is turned off. It is normal that it is difficult to start the car after cleaning, because there is a lot of cleaning liquid in the accelerator. After landing, you can fry a few feet of oil in situ and discharge the residual cleaning solution. You can drive when the idle speed is normal.

The old Jetta needs a computer reset after washing. I wonder if the new Jetta is needed.
