    I removed the ERG from my 97 SOHC. I have vaccum tool.

    I think the ERG should hold a vaccum (?at least for reasonable tme?)
    When I tested mine off the car: I applied vacumm to it an saw the inside valve droup closed very quickly.
    I have vaccumm to the erg while the vehicle is running so I suspected the diapham in the ERG
    Any takers?

    You are correct. The EGR should hold vacuum and remain open (with vacuum applied).
