WARNING: This page is about a different car, the 1999 Acura 3.0CL. However, it is still accessible from the selected car via links, so may be relevant.
Disconnect lower vacuum hose from engine mount control solenoid. Connect a vacuum gauge to hose. With engine idling, manifold vacuum should be present. If manifold vacuum is not present, check for leaking vacuum hose or plugged vacuum port. If vacuum is present, replace engine mount.
