I'd take a look at the up&down stream differential pressure sensors checking for voltage(at idle) and ohm them out(though I don't know the proper resistance offhand but 0=bad)

I went through it and cleaned the MAP and MAF and checked everything. Did not really find anything. Had to make a 30 mile drive and basically turn around and drive back so figured it would be a good test run. It did the same old thing, get in it and it start a regen and then the go see the dealer message. I pull over and reset it with the computer and keep going. I got mad at it and started driving it like a stole it and every time I did it got better and better. It went from 100% to 90%, then do it again and it would go from 90% to 80%. Currently down to 2 on the soot load from a start of 10.
