To be sure there are no leaks disconnect the hose at the manifold and plug it similar to the brake hose test just to verify that is not the culprit. You should be able to take a vacuum reading with your hand pump on any vacuum hose coming directly off the manifold. Assuming your car is the same as mine, my suggestion would be the lower of the two small nipples on the passenger side of the engine under the fuel rail cover, it should go to a "Tee" with a check valve in it. The line to the Tee provides vacuum to the A/C controls. The top nipple goes to the fuel pressure regulator, removing that one might confuse the issue since it will run richer with the vacuum line disconnected. Also check the vacuum line to the cruise control servo, seem to recall that one is fairly large too, try to plug it at the source to eliminate it from the list of possibilities, good luck. |
