Trying to troubleshoot emission problem. Getting trouble code P 0401-EGR SYSTEM FAILURE.? - free code for mount and blade

I have the EGR valve in my 1997 Chrysler Concorde 3.5L six days. On the replacement of this part, I drove over 100 miles in 5 different increases. I was told that after three cycles of the unit, the check engine light should go their own way. Well, its over. I have the same difficulties with reading code analysis tool DRB III P0401. Then set the code and took about another 60 miles came back the check engine light. Then I went to a muffler shop and had performed a pressure test on the two new catalysts and that the work was good. They told me that some carburetor cleaner and spray into the consumer arena, where the EGR valve mounted on the motor to loosen the carbon accumulation. The problem is, how do I get the backlog of liberation? Or is this a good method? Or what else should I try it, right? Any help would be very grateful. I try to pass my emissions test. You still have 9 days to deliver. Could not the first time because of this problem. Someone please help.
