Throttle body exchange on Roomster 1.6, 16v auto, BTS engine

I am looking for advice re. our 2007 Roomster with BTS engne and auto-box.

After experiencing EPC light a few times, and some jerky throttle response it seems the throttle body needs replacing on our 2007 Roomster 1.6 16v auto.

A throttle pedal swap with a known good one made no difference - still getting a 'kerk' sometimes when changing throttle setting from a steady speed.

And, more throttle lag / slow response when setting off even when engine is warmed up.

Plugs + air filter are good etc. EPC light goes off when engine re-started, and can be Ok then for a couple of journeys.

No split air pipes found.

Throttle body seems to be the culprit and its cheap and easy to replace.

BUT - question 1:

Does it need re-alignment after replacing? Or, will it re-learn by itself after re-connecting battery and leaving ign. swithced on for a few minutes?

AND - question 2:

If it needs re-alignment after replacement, is anyone in Derbyshire (we are SK17) able to assist with this?

I don't have diagnostic kit and our local garage is not experienced with this sort of thing.

Advice would be much appreciated
