Question Code 31 After Upper Intake Install

I took off my Edelbrock Performer 5.0 Upeer Intake to retorque the lower intake bolts because of a coolant leak. Put evrything back on and now I am getting a check engine light. Ran the codes and got #31 EGR. Didn't have that problem before. Everything is hooked back up.
Any ideas on what to check or what I maybe screwed up or forgot to do?
