    It sounds like the idle control is not plugged in. Did your car idle high to begin with. When I set up the base idle on my car and I unplugged the idle control on the back of the intake, I brought the idle up to 1000 rpm it would jump up and down similar to how you described. Maybe the plug/wires got damaged during removal.

    either idle control isnt plugged in or the wires are damaged...
    the fast idle control-on the back of the manifold there are 2 coolant hoses try switching them arounf
    or its a vacuum leak<----most probable

    1000-2000 rpm idle jump usually indicates a vacuum hose on the intake manifold. Look on the back of the manifold, im sure your missing a hose somewhere or it was not connected back up.
