I see these codes all the time in Fords and it is nearly always caused by a severe vacuum leak. What usually happens is one of the large rubber connectors or PCV hoses collapse and suck a hole right through them.
List for a hissing noise at idle and try to follow it to it's source using your fingers. The sound will change when you block it.
