1999 Mitsubishi Galant Car shuts off after recent battery p

Hi gettinmyhandsdirty. Welcome to the forum. If this is a new problem that just started after the battery was disconnected, the Engine Computer most likely just needs to relearn "minimum throttle". I can't say for sure with your car, but for Chrysler products, that takes place while driving the car. The conditions for this to occur include driving at highway speed with the engine warmed up, then coasting for at least seven seconds without touching the brake or gas pedals. At that point, the computer memorizes the voltage from the throttle position sensor. The next time it sees that same value, it will know it must be in charge of idle speed. Before that value is learned idle speed will be too low, and stalling at stop signs is the most common symptom.
