Since these cars are all 20+ years old, sometimes the plastic vacuum lines themselves get really brittle. When you're leaning on them trying to fix something else they can crack or break without you knowing it. The MityVac is the easiest way to check but if you don't have one available start by looking at the plastic vacuum lines and the rubber attachments really closely. If you find a broken line a quick fix is reattaching the line at the break with rubber vacuum hose. If you push the two halves of the old plastic line together inside the rubber "connector" it holds them tightly together and won't collapse under vacuum.
