I haven't done any of that yet. I'm planning on taking the TB off today and rooting around in there. I assumed there was no IAC due to it being throttle by wire.

I do have another question. If the TB is removed from the vehicle, can the butterfly be moved slowly to clean the back side of it and the edge? I have seen videos and forum posts saying it's ok to do so, while others say to never manipulate the butterfly EVER. I won't be flipping it rapidly, just slowly open it to clean it thoroughly, while trying to not strip the gears inside.
