Re: rps at idle
It is called Idle Surge.. the cause of it could be many things, cleaning the TB helped a bit for me. Search for idle surge for other stuff that could cause it. It is not going to hurt anything so i would not go change ever part that could be causing it. Not worth it IMO, unless you reallly cant live with it.

Check your TPS sensor . Its usually the culprit of an idle surge. Either its dirty and needs cleaing or you need a new one. You can find it on the throttle body. Take an ohm meter to check it.

Re: rps at idle
^^ Yes! Use an ohm meter... Don't try to adjust by just the screw on the front of it.
 (yes I've made the mistake myself)  That's if that's the problem.
