Yes, a flooded engine can clear itself out, but it might take some time. If you've flooded your engine by attempting to start your car several times, the best course of action is to wait it out for about 15 to 20 minutes before trying again. During this time, keep the accelerator pedal to the floor while turning the key in the ignition. This action signals the car's computer to reduce fuel flow, aiding in clearing excess gasoline from the cylinders.
