does anyone know what this start valve does? Currently i am having problems when starting my car when it is cold. It takes 3-4 cranks before it starts. When starting the engine will catch then die, catch then die, catch, then idle real low and then go right to normal idle. Once the car is started it runs like a dream. I am attaching a diagram of where this valve is located and if someone can tell me if they think this could be the cause of my problem let me know!
