Hmm...browsed through that thread. I've been thinking my idle problem is vacuum leak related from bad lines (bought new lines and will replace soon anyway) but maybe upgrading to the 2.0T coils is my issue. My idle will drop to 500rpm or even less at times. Not repeatable and some days is worse than others but no real pattern. And its been driving me nuts. Will be researching this more for sure...
