If it's equipped with the 2.0L SPI engine (eighth digit of the VIN is 'P'), the most common place for a vacuum leak on these engines, is from the PCV hose that runs from the valve cover to the back of the throttle body. Where it usually rots through is the elbow at the back where it connects to the throttle body. Hope this helps. The only place i could find any views is here. vacuum hose diagram - Focus Fanatics
