check the cloth covered vacuum hoses and look for one disconnected.

Default I had the same problem a few months ago. Check the link to a thread further down the page...

As SharkAttack said, one of the vac. hoses could be disconnected, but they tend to get brittle over time, so changing them all will save you the pain of doing them one at a time as they start to fail.
