i have no vacuum.  the two inlets on the egr spacer are open.  i have no hoses going to them and i dont know how i can fix it.  i dont know anything about the vacuum system.  if someone can direct me to a site than can tell me or show me how to fix this problem i would greatly appreciate.  or if anyone can tell me how to fix it that would be good to.  can i just buy something to put over the inlets or is there a way that i can fix it.  the 5.0 isnt the stock motor, it was an original four cylinder.  hope theres someone out there that can help.  thanks.  

I cut a plate to fit over mine. i havent seen any negative effects but my car would never pass emissions. if you have a stock exhaust manifold make sure to plug it off as well
