Why does my car stall when I go through water?

Why does my automatic car stall when I come to a stop?

Why does my car shut off when it’s cold?
The problem occurs when the car is transitioning from cold-start to normal run conditions. If the coolant temp sensor is faulty and tells the computer that the car is all warmed up when it’s really not, the computer might then reduce the amount of fuel going into the cylinders, which could cause a cold engine to stall.
How do you fix a Hydrolocked engine?
First, the water must be removed from the cylinders. The spark plugs are removed and the engine is cranked over. In engines that were hydrolocked at idle or when the engine was not running, it may be all that’s required to clear the obstructing water, so removing the spark plugs isn’t necessary.
