There is only one thing I can think of, but I don't know for sure so I need some feedback.
The Vacum Tree coming out of the */C. The O-Ring that seals it at the bottom was getting pretty old and cracked, I reused the old one cause I had to wait for the new one to come in from the USA. I have the new one but haven't installed it yet.
Could this be the cause if it is leaking ?
I don't think there are any other vacum leaks cause the car idles better than ever (nice and stable) and all the lines looked good.
