it does it even when the car is parked. i mostly only hear it around 1530(ish)rpm. forgot to mention that i also have a slight coolant leak that i feel could be the cause of it. car runs fine otherwise though, just makes strange noises and idles rough.

i just replaced the coil packs and it stopped having a misfire (said cyl 1 and cyl 2) and i still have the check engine light, but i haven't rescanned it since i fixed my misfire due to not having enough time. car is also due for an oil change but i don't think that has anything to do with it since it's sounded the same way 10,000 miles ago.

i am going to try to replace spark plugs to fix my rough idle. i just replaced my valve cover gasket but didn't have time to replace the spark plugs yet. weird noise started happening after i hit that pothole-ish thing so i hope it's just a hose that came loose or something.

i have a video attached to the original post that you can watch and i'll send the link again.

if needed i'll record another video tomorrow from the outside to see if that helps you hear it better. it's definitely something coming from the engine bay, but just not sure what.
