P0011 Code (list of those affected)

Been running great the past year, until last week...

Figured I may as well add this here, too... This time P0021

1. '03 Variant Tip
2. 21 Jan 2013
3. ~121,000 mi
4. First, I just shocked the solenoids for bank 2... not much improvement. Dumped in some SeaFoam, then shocked both banks. I've noticed some slight improvement, even a full day of completely smooth running, ~150 miles. Rough idle seems somewhat intermittent now, and less noticeable most of the time. Planning another round of shock, followed by an oil change this weekend. Hoping for the best...

Thanks... we need all the luck we can get with these beasts.
