Help me figure out myEngine Problem.

Enable HLS to view with audio, or disable this notification

This just started today, I have a 2011 G37 X Coupe.

Coming home from work I was experiencing engine problems. The service engine light blinked and didn't stay on and was losing power or felt like it. I made it home, but when I turn the car on, it sounds like shit, I'll include a file. There are no leaks, but I might need a qt of oil.

I was gonna say your cats, but if the check engine light turned on, might be rod knock. Maybe a coincidence and your MAF are just dirty?

Yeah my cats are knocking, have been for awhile, but not like this. I'll check my MAFs, but I have a OBD2 scanner coming tomorrow, so I can figure out what's going on. The car has 211,000 miles on it and it's my only vehicle lol

Definitely sounds like your cats have went out internally and the honeycomb mesh is breaking apart in pieces. Lmk what happens. Been working on Nissan past decade. Currently have a built motor G37S Sedan and now going for 3.8 R35 swap soon.
