Default HELP 2008 335i N54, weird noise - 06-18-2020, 01:21 AM

I'm getting a weird noise whenever I accelerate, even in neutral/park. It's not really there where I accelerate slowly, only when I tap on the gas quick. I am getting a code for a misfire in the third cylinder, but that's it for codes. Car feels fine when driving but this noise sounds sketchy...help...

Sounds like a vacuum line or hose.

Can you feel a vibration if you touch anything there, like top of coils, injectors, valve cover?

Me or my dad didn't feel anything vibrating in those areas, no
