How do you test the EVR it seems like mine is not working?
I run High rpm and check vacuum at the same time at the egr however it seems like the evr is not enrgizing to send vacuum to the egr. Is there a reliable test that can be performed. 89 302
When mine went bad it was leaking vacuum. The best way to check it is to remove it and use a hand-held (Might-vac) vacuum pump. Plug the outlet, and attach the pump to the inlet. Pump it up and see if it holds.
Those Mighty-vac pumps are invaluable for checking stuff like that. They are certainly worth the investment.
