Alright so my Jetta is misfiring and throwing codes P0301 and P0303, so it's misfiring 2 cylinders. I can hear a hissing noise coming from my engine bay, like a vacuum leak noise, I'm not sure where the leak would be, I wish I could upload a video so you can hear it. where could it be leaking from or what's the most common area. The noise is coming from the drivers side of the engine bay. The coilpacks and plugs were just changed so what else could it be. And if it were a vacuum leak where should I look first.

In the picture I show where the area is the noise is coming from
