Hey all...

I've been hearing a weird kind of whine coming from the (if you're facing the front of the car) lower left of the engine bay. It's almost like it's below/off to the side of the serpentine belt, and is most noticeable when you turn the car off you hear a squeak/squeal for a second or two afterwards once the belt has stopped moving. Any ideas what it could be? It doesn't really come out on my video recording so that's not gonna be a huge help unfortunately, also, does the rest of the engine sound okay to everyone as well?

If anything sounds off please let me know, I've been wanting to do my spark plugs since my car just hit 102k but the sparks that Advanced Auto sold me were way too big (16mm and huge threads) so I had to back out of that at the last minute.. It almost sounds like the car is chugging to me

 

So I had to reset the throttle body zero and accelerator zero and it smoothed out big time. However, I still have the slight squealing sound coming from the lower left of the engine compartment (left and sounds like lower than the belt assembly)

Anyone with any ideas is greatly appreciated, thanks!
