Chris:

I think there's a couple of problems with old EGR valves.

As I recall, there's a sort of dome-shaped rubber gasket that goes around
the shaft that moves back and forth in response to the movement of the lever
arm.  This gasket can disintegrate over time allowing an air-leak past the
shaft.  Too, I think the 2 seats inside the valve that shut off exhaust flow
into the air distribution chamber wear and pit over time such that the valve
isn't sealing properly at idle and WOT.

At this point it probably doesn't hurt to try cleaning the valve and see if
it'll work.
