Thanks for this thread. Add one more to the list. CCV to dipstick hose 11157532649 was completely cut below the elbow. RockAuto had the URO replacement hose for $7.07+ship. With the airbox out, I also cut an inch off both PS reservoir hoses to stop small PS leaks.
- low idle surges when cold (I'm unsure if this is fixed yet.....)
