Check Engine throwing code P0401
So I recently had my 02 Ranger in to AAMCO to get the trans fluid flushed, filled and a new filter and gasket, it's got just over 100k on it and it was last done around 67k.
Anyway I also asked them to hook it up to a computer and let me know why my Check Engine light was on and if it were a sub $150 repair to just go ahead and do it. I got a note back that it was the following:
P0401 = EGR insufficient flow detected
and that they would need a day to determine the causes and it would incur diagnostic feels at $100\hr. and so on. So I told them thanks for letting me know what it is and I'll see if I can fix it myself, if not "i'll let you know" (yea right).
I see that this code is plastered all over this forum, but I wanted advice as to where i shuold start. I already replaced the little elbow right to the left of the trottle that was worn out with a crack in it.

UPDATE: so the P0401 code still exists, I got an Android phone and am using a bluetooth OBDII chip with the Torque app so I can scan for the codes it's throwing and it's only this one. I had a local shop replace my EGR valve as thats where many of the posts on this form pointed, I pulled the battery to clear the computer, but after about 70 miles the light came back on with the same code.
What should I look at next?
