I am also getting a code that states there is insufficient flow to the EGR.
I just had the intake gasket replaced. Everything is hooked up properly.
The car runs great and idles well. I'm getting 30 MPG.
What's it take to replace the EGR? I can get my hand on the bolts.
Any reply is appreciated.

Take a look here:

This guide gives a nice explanation of how to remove&clean it...I would try that before replacing it...
