The EGR should only circulates exhaust fumes back to the intake manifold.
As I said above you may have got the problem taken care of, but watch the EVAP system for any trouble.
The solenoid is normally closed; Adding vacuum to it should be negative, but adding vacuum to the line that runs to the rear of the car is what you want to test.
