Hey guys, I picked up a used s90 throttle body from a member on here a few days ago but I noticed the plate seemed slightly open. Before I go about messing with it or installing it the way it is, I wanted to quickly check with everybody to see what they thought. Thanks

It looks like he had a full block off cover underneath so he set it cracked open to help idle since it had no ISC to control it.

You can either install the lower section and run the ISC or keep it like this, its just harder to keep idling right when cold
 
Looks open a little too far. I would say the opening should be between a sheet of paper and the material a band-aid box is made out of. The rest should be handled by the ISC (if you use it) and the BISS. I have an s90 and the gap looks close to the stock throttle body gap.
