When Jed stopped washing the car, he accidentally put some water into the intake pipe. Can he start the car again the next day?

It was ok to start the car at that time.

You don't need to start the car every other day.

Because of the lower part of the air inlet, he has a drainage hole. Water will be discharged from the drain hole. Don't worry, the engine will get water.

As long as the water is not too much, it has no effect at all. If there is a big ladle of water, it will have an impact.
