The proceedure for checking the EGR is posted by me below. You do not need to plug the vac hose for the EGR valve when you remove it. There should be NO vac when at idle. If there is a vac going to the EGR valve at idle, then the DPFE is very likely the culprit.
Good luck guys.
below? or above? lol.
Gotcha - to be sure I did the troubleshooting correctly, I just came back from Autozone during lunch and picked up a Vacuum Pump from their loaner-tool service.
They have one there for $25.99 but it was plastic and I didn't know how good it was....Probably should have picked it up for that price...but oh well.
I will be testing the EGR later on today when I get home from work.
Thanks!!
