This is a very old version so I can't recall the exact location.
It should be under the throttle body or somewhere nearby. Look for a cylindrical component on the intake manifold with a cap held by 2 screws and has 2 hoses at the bottom.
Btw check the idling speed, if it is too high, surging would occur. So would leaking vacuum hoses, check for any that is dislodged.
