By “floods” I mean “giving it too much gas when trying to start it.” What’s the best way to remedy this? Does the problem just go away on its own with time?
I’ve never seen a modern automobile with fuel injection flood. Back in the day of carburetors, flooding was usually fixed by depressing the accelerator all the way down to the floor and holding it while cranking the starter until the engine started. Do not pump the gas pedal, that’s what got you flooded in the first place. Someone with more recent experience will be along shortly, so don’t take this to heart.
Flooding is much less common than it was 20+ years ago, but can and does happen occasionally. It will go away on its own - the extra gas evaporates eventually - but sometimes that takes hours. Interestingly, the procedure to deal with it is the same as before. As far as I know, all modern fuel injection systems have a “clear flood” mode in which the injection of fuel is stopped if the accelerator pedal is held all the way to the floor while cranking the engine.
If you find that the car often or routinely floods, that indicates something is wrong that needs to be fixed.
Many but not all. To the best of my knowledge Bosch systems do not have a clear flood mode.
