Yes I did get 332 again after cleaning the passages and resetting pcm. What about that super thin line which is hard, only somewhat bendable, and is a light faded green, almost white in color? Its attached to a T-connector which attaches to those passages behind the TB. That thing looks like it could get clogged easily, although mine seems to go downward toward who-knows-what after a few inches so I have no idea if it is related to EGR flow. I tried to spray a little carb cleaner into it but to clean it I'd need a very thin reamer of some sort. I won't mess with it unless someone suggests it. Maybe I could get to the other end of it by jacking up the car and going underneath.
