Throttle fully open

Idling the engine tells you not to step on the accelerator where it is not running.

Full throttle is full throttle. I told you not to drive like this for a long time and not to drive too fast.

3. Avoiding washing the car when the throttle is fully open means telling you that the air intake system sucks in the outside world, especially when the throttle is fully open, and if you wash the car at this time, the water from washing the car will be sucked into the engine, causing engine damage.
