So While I was flushing the antifreeze I decided to clean my idle control valve as well as the throttle body. When I took it off and cleaned it I noticed the two ports for the coolant were rusty and kinda clogged also with a bit of pitting going on. I cleaned all the crap out of the two air ports and replaced the o-ring. my question is should i plan on replacing ICV? Car is idling much better no problems so far.

 

If it is idling better...than let her roll I say.
