I'm back. Wish I has as much to offer as those who have helped me here.

1994 T100 3.0L V6

The check engine light is on and the code is complaining about the EGR valve. I pulled the valve and it's free. The diaphragm seems ok. Vacuum lines are ok. Anyone know how to test the thing. What's the voltage into the connector? What resistance should the valve show.
