    I don't remember if the EGR solenoid on the '95 is vacuum or electrically
    activated. having said that, I'd suggest you make sure that the vacuum hose
    is not cracked or leaking if it is the former. In fact at that age, I'd
    make sure that all the vacuum hoses are good since a leak in any would
    reduce vacuum in others. Also, when you had the EGR valve off, did you
    notice if the exhaust manifold or intake was plugged which could affect
    proper operation?

    Good luck.

    Yes, the EGR solenoid is electrically on the 95. I check the manifod intake
    is see. When I changed it I looked but not very closly to see if the was
    pluged up. What confused me is that check engine light turns on when it
    is cold out side?

    Thanks for the help...
