Buy a Helms. I don't know how many times I have to type these instructions, but I'll do them again:

1) Buy a new EGR Gasket and new TB gaskets
2) Remove intake
3) Remove TB (don't mess with throttle/cruise cables, just set it down next to your battery or something)
4) Remove IM
5) Clean IM EGR ports
5) Remove EGR Valve
6) Clean EGR Valve ports

And that's it. I don't have the torque specs but you'll get them from a Helms or Haynes. Everything is probably between 15 and 20 lb-ft since it's all aluminum. But if you don't get or don't know how to do anything I just said, buy a Helms or subscribe to www.alldata.com.
