All of a sudden today, several times the car stalled as I was driving.
Subsequently, the car couldn't start and appears after several attempt the
plugs got flooded. It seems that there is an issue with that which
regulates the rpm's as before the car stalled the rpm went to 0 suddenly. I
change plugs and gas filter today so after the car stalled once I could
drive it. The tank is full of gas. The starter is cranking fast The
battery helps the starter crank fast. What could it be?
