I am having the same problem right now and have posted here this week. No answer yet. I did replace the easily accessable Vacuum Check Valve and a smalll piece of Vac hose but still have the same problem. I hope that one of us can get an answer. I was told by Ford Service that there are TWO Vacuum Check Valves for mine (2003) that he pulled up on the computer but he did not know where it was located?
