i take it that you dont know exactly where your vaccuum leak is coming from. what makes you think you have a vaccuum leak? check the sticker under your hood. "might" show you location of egr.(just follow the numbered lines) but otherwise the egr is near the distributor. behind the valve cover. in front of fuel rail. directly in line (pretty close directly in line) with vtec solinoid. spray brake cleaner around where you think you have a vaccuum leak...idle will go up if leak is there.
