Idle speed high after throttle body cleaning 3.4

'95 T100 3.4 automatic.

Yesterday I pulled the intake snorkel from the throttle body and
cleaned the gunk out that was on and around the throttle butterfly. Of
course, I did it with the engine off. Quite a bit of crud too.
Upon putting everything back together and starting the engine, my idle
speed is now probably 1200 RPM according to the tach. The manual
specifies 650-750 in park with the engine at operating temp. I've
disconnected the battery in an effort to "reset" the engine computer
since I thought that with the different airflow parameters after the
cleaning that the computer would have to relearn data from the idle air
control valve.
So anyway, can I reasonably expect the idle speed to return to normal
after a few days/miles of operation?
Thanks for any knowledge you can send my way.

You might have damaged the Idle Control Valve that the ECM uses to
controll idle speed. It is electrically controlled.
