bad idle following battery disconnect/reconnect

I replaced my steering lock mechanism, as the old one went bad.
Upon reconnecting the battery it did not want to idle smooth. It was up and down, close to killing with out keeping on the pedal some.

Will this straighten out? Is it a normal occurrence ? I've looked thru many threads on this procedure and thru my manual but don't see much. Seems before doing this I had seen someone say that the a brain had to re set or re-learn for a while. Is this true?
Everything else that was bad is now fine, no more sticky key , electronic locks working now,

Anything I should check or test.

Try this...
Disconnect the battery again.
Touch the positive (+) cable to the chassis for a few second to discharge any capacitance in the system.
Reconnect the battery and switch on the ignition - but do not start the engine - leave ignition on for at least one minute.
Switch off ignition for at least 10 seconds.
Restart engine.
It may take several miles and about 3 - 4 heat cycles of the engine temperature to completely reconfigure the system.....

Don't forget to program the windows too. Roll them up. Let go of the switches, then push and hold in the up position for 5 seconds.
