Default Audi A4 b5 1.8t Quattro low fuel pressure and all cylinders misfire

Hi there,

Before I go any further, I my self is a mechanic but having issue locating the problem on my Audi.

I started getting low fuel pressure code, so I changed out fuel filter and fuel pressure regulator, it did not fix it. The car has s very rough idle, runs good soon as you accelerate a bit, also the vacuum is only about ten, but when you add rpms it builds up to 32(vacuum)
Drives fine, I thought maybe the vacuum lines are disconnected somewhere or a boost leak and found no issues. I am so confused with this thing it's killing my pride lol

Any suggestions or similar problems
