So yes I definitely had some vacuum leak somewhere but not only… one of the direct injectors came out faulty and not spraying properly.
I learnt that the engine uses sometimes more the port and sometimes more the direct injectors depending on the rpms and engine load, so I guess when I was soliciting the engine beyond a certain load at a certain rpm, it starts to use the DI and that’s why the misfire and shaking happen there.
I’m getting a new injector soon and will keep this post updated for future reference.
