Are there any how to's for changing the EVR, DPFE, and EGR, or at least any pictures? I have the 0401 CEL. I have checked the back of the TB and the EGR ports are clean. I have also done the vacuum test on the EGR valve. The RPM's did drop which leads me to believe that the EGR is good. I plan on attacking the EVR and DPFE first.

Thanks in Advance
