So my tech thinks my EGR valves are not opening due to inadequate vacuum. But I have not had any codes with other vacuum dependent systems such as waste gates or diverter valves.
Any ideas??

This sounds like the ongoing issue with low vacuum that you've been dealing with. I don't recall from your other thread, but have you checked/replaced the brake booster pump?

Maybe you can plumb a cheap vacuum gauge temporarily into the system and try to get a read on what exactly is happening with your vacuum levels.
It's sounds like an intermittent issue with borderline vacuum, which is a tough one to diagnose.
