Hi iv got a p1553 barometric/manifold pressure signals issue.

 

Some research suggest checking for vacuum leaks.

 

How and where do I check for leaks. 

 

Iv added picture of my engine.

I also have a slight kink (not shown in the photo) in the pipe from which I'm pointing.

feels engine slow or normal?
i have that code on a bby on a audi a2 and its precat that died and blocking the main cat and that car is slow asf.
