Ok, I just got my scan tool today and found out that I do have the dreaded code P0401. I don't have the FSM so I'm not sure what the procedures are to determine what is broken, but I decided to poke around anyway.
I took the advice I had seen on this board and checked the EGR vacuum modulator (that's what my great Chiltons calls it). Now I'm not really sure this is what people were talking about when they were talking about a filter. Is there also a filter in the EGR valve?
Anyway I took pictures of the modulator and filter that was in it. Apparently the detailer at the dealer that I bought the truck had no qualms about using 100 gallons of water to clean the engine.
So here are the pictures... what do you all think... sorry about the quality, I'm still trying to figure out how to use the macro on my camera. As far as I could tell it looks like someone tried to use the filter for their charcoal fish-tank, or tried to use it to strain coffee grounds.
