Why did my car stall after driving it through a big puddle?
>for gasoline fed engine. it is possible that water came in
contact with high tension wires/ignition coil, and other electrical
parts supplying to the ignition.
>another is , it is possible water is sucked inside to the
engine by passing through the air filter.
>another is when water level outside is above the height of
the exhaust pipe, to prevent engine from stalling in this situation
is only to increase RPM, engine rev.
