Sorry I wasent sure how to approach this so I started a thread. While this section is a great idea it seems like the surging idle is a more mechanical related problem and not so much of a TwEECer/related editing program issue. jrichker put a lot of effort into that thread and I would hate to see it overlooked by the newer members of this site trying to fix a VERY common problem with our cars. I know I would not check the "Tuning" section of the site for a Tech related problem if I were new here. Just a thought At any rate thanks for puting up the tuning section, I hope to soon make use of it :EDIT: Yes I did read "Purpose of this forum". It just seems most of the Fixes for this partucular problem were mechanical in nature; i.e. vac leaks, dirty IACs, rotating MAF sensors, etc. etc.
