Ever experienced engine stall with air-conditioner on when you car slow down? What if its happen at the moment when you in a middle of U-turn? I bet your heart will pounding rapidly.

FICD is a little device that will help you with this problem. The concept is, this device will allow vaccum leak by allowing more air into intake manifold hence engine have enough air and wont stall. Its also stabilize idle and drive will feel a little bit lighter with a/c on. For the one who familiar with valves, FICD is simply a solenoid valve.
