98RL Check Engine Light code P0401

Probably belongs in another forum but I was hoping for some dealer input also.
Getting a code P0401 (poor EGR Flow) on a 98RL (106k miles). Egr valve and pipe and riser clear of carbon, valve holds vacuum. When I force EGR valve open idle drops a little but engine does not stall.
I see Helm has a Bulletin called - Mil On With Dtc Code P0401. Does anyone have access to this information already? I haven't approached my dealer yet as I was hoping to repair it myself or at least be better informed before I go in.

Thanks for any help/advice.
