On the V6, it is two bolts, and pull it off, slap on a new gasket and tighten the two bolts again.. nothing else is taken off.
Check for a leak or crack in the green vacuum tube on top of the EGR first. if it comes off, or cracks you will get the same code.
You can test the EGR by sucking on the nipple of it (pull the green vacuum tube off) and see if the car stumbles while running. If it does, the EGR is good. look elsewhere for lack of flow (vacuum tube I mention first, etc)
