If you think you have a vacume leak crank the car if the car wont idle normally crank it and pump the brake, if the car idles fine then its a vacume leak.

Mine was the engine intake manifold gasket causing the problem (leak).
But only after replacing the ACT, ECT sensors, IAC Valve & gasket and cleaning throttle body.
