In short yes, and makes it more difficult to control cus of how easily it moves. If I were you I'd just unhook it take a plastic bottle 2L bottle cap cut it to fit tightly in the valve then pull it out cut a little sliver in it an see where it idles. Keep cutting slivers till you get the cold idle around 600. Once you get it to that point it'll idle around 800-850 when warm.

Ok, I took the throttle body apart and made sure the TPS was working correctly. I put everything back together with new gaskets and I still had the issue.
I happened to notice a missing valve cover nut! I'm not sure if this would cause a big enough leak for my major idle issue, but I'm beginning to wonder if the shop ran the smoke test correctly. I will try and get another one done somewhere else and hopefully witness it.
In the mean time, I resorted to the ol' penny trick... so I don't go crazy at red lights. :|Comment
