I've removed the TBs on three different Z's to clean them. Definitely moved the butterfly valves a bunch to thoroughly clean them. All I did after was the idle air relearn procedure (takes ~25 sec). IIRC there is another, more complicated reset procedure that should be done if the idle air relearn does not suffice.

I had intentions of not moving the butterfly valve while cleaning. But these cars had 35K, 50K, and 70K miles on them, and there was no way I was removing the line around the valve without moving it. I used a hard plastic toothed brush to clean them with great success.
