You should recheck your vac line work, EVR must vent to atmosphere to allow the EGR valve to close when the computer turns off the EVR to do so.
If you have the two vac lines on it reversed it would hold it open, at least until vacuum slowly leaks off allowing it to close if it at all would depend on how vac tight that section is.
Would or should also create a vac leak for the engine have trouble moving the EGR valve, again depends on how healthy the motor is how much vac it creates and how vac tight the supply is to the EVR in that condition.
