Where the vacuum connects to both the intake manifold and the valve cover there are rubber seals that get hard. You might take a look at these, I have found that wrapping the plastic peice that slips into the manifold with electrical tape will help out for a while. At least that will work long enough to order the seals.
You said have replaced the plugs and wires, but did you also replace the cap and rotor? That could cause low mpg. My experience has been that minor vacuum leaks cause most of my problems.
