... loosening the two torx screws on the plate.
This may allow the butterfly to settle back in place (if the TB hasn't worn too much. I highly doubt it has).
Once the butterfly settles in place, hand tighten one of the torx screws and remove the other one.
Put locktite on the threads and tighten in place.
Remove the other torx and repeat.
If the butterfly has settled back in place you should not see light around it, when held up to a light source, just at the place where it wore down.
The little bit it could have worn will not affect the idle, because the butterfly will still have to open somewhat to allow more air through.
Happy Porsche'ing,
