Easiest wayto track down a vacuum leak? What is the easiest way to track down a vacuum leak on my car?
Finally got some time and some down time with my car and I think I have a vacuum leak somewhere on the car but not sure how to locate it or find out if I have one at all.
Thanks

I think the quick and cheap way is the use a can of spray carb cleaner.. spray a little (enough to soak the area) around each of the vacumn area that you suspect to be a leak.. if the RPM change.. you found your leak. PCV, Power Break line, intake manifold, TB Gasket ... etc..
This is an old trick that is used for Carb cars but work for EFI too.. been used as long as I can remember.
