Most common restriction of EGR vaccum ? Most common EGR valve failure ?

I see no reason to assume the EGR system is the cause of dying while driving, especially if the EGR is restricted or not working! There must be more to the story. We have seen so many thing that might cause the problem that there would be no room to write them all. If you call we might be able to help you plan the next step. Thanks, Dana
