    low vacum pressure

    my buddy took my car to work the other day to see whey my check engine light kept comming on. he found i had low vacum pressure, it had 10lbs and its supposed to have 18 or so. has anyone else had this problem? is it probably jus a leak in a hose or could my intake manifold gasket be leaking?

    You should be able to hear a vacum leak , although you can use some soap and water to find it. Have you replaced the manifold? check all of the exterior lines, ie brake booster.
