car stalled while driving

Your Nissan has on board diagnostic capabilities. There is a 16 pin diagnostic socket under the driver's side of the dash, a generic or Nissan scan tool can ber plugged into the socket, the tool communicates with the computer in your car to see what fault it saw that caused the check engine light to come on. The engine has many sensors that if they fail or fail intermittently can cause the engine to stall, Hopefully plugging in a scan tool and retrieving the stored codes will point directly to the problem.Amco and some auto parts chain stores plug in the scanner for free.
