Any CEL codes? Check for a disconnected vacuum hose. Did you remove the TB or IM?

When you disconnect any coolant hoses, like those on the IACV, the cooling system must be bled. Air in the cooling system also can cause a hunting idle.

Did you bleed the cooling system? If so, any effects?

You also might try adjusting the idle screw on the throttle body as detailed in the service manual.
