There are two types of 'bad' valve one where the diaphram is split and one where the spring is weak. You can test the first type by pulling off vacume hose and sucking on the end to see if it will hold vacume. You can hear if the spring is weak as it will howl or hoot as you go from negative to positive manifold pressure. Any Saab dealer will supply the part. Johann
