Common problem with renix, both of mine have done that. My old one did it no matter what, this one I finally have it at 750 where its supposed to be.
Get some carb cleaner and spray it around the manifolds, vacuum lines, TB, etc. Listen for the idle to change. If the idle changes you have a leak and need to do something to fix it.
If it still does it after that, I would clean the IAC. Still does it after that? Adjust/check tps.
Fill out your info, too...
