Well that has fixed my rise / fall with the idle. Whenever I first put my throttle bodies in I set the stopper at what I thought was exactly at close. So to test your idea I backed the screws down to where they didn't even come into play. Now the rise and fall of the idle is gone. Thanks! The only issue left with my Z now is that it still has a rough idle, but drives / boosts fine. I am going to start pulling coil packs today try to find why that is happening.
Thanks again!
