Two place's to check for a vacuum leak first the hose that goes from the back of the throttle body to the map sensor.The elbow that goes on the back of the throttle body get's a hole in it.Also the hose that goes from the intake manifold to the pcv in the valve cover get's a hole it.Check those two thing's and get back to me.
