Welcome to Just Answer! My name isXXXXX will be happy to help you out and your 100% satisfaction is my goal. Please realize that all my answers are based solely on the info that you provide me with....

 

It sounds like you might have a vacuum leak or the fuel pressure regulator is leaking fuel into the intake causing your stalling. This is very common. When this happens, two things happen. Your fuel pressure is low because your fuel system is leaking and the extra fuel goes right into your engine and its not accounted for by the computer. The combination for both of these things can cause all sorts of problems and most likely is the cause of your surging problem.
