WHY IS MY NEON MAKING THIS SOUND?

Unplug it and see if sound goes away

Are you sure sound isn't just traveling from the actual source up to that plug?

100%, I checked all the metal surrounding it and nothing, I checked everything. It was loud on that device, it sounded like a small electric spark coming from inside of it.

Unplug it and then just Google your wiring diagram to see what it is, I could tell you exactly what it is but life I say your neon is older than mine so it's prob something in a completely different spot on mine

Did you unplug it?

Its making that sound because its bad. Replace it or just unplug it and go on with life

No one here even knows what it is, what if the engine blows up if I do that?

I do, its the purge valve. Replace it if you are afraid it will blow up but it wont.

that is your engine mount sir.
Vacuum switching valve. Had a similar structure on my 1uz.

Thanks guys.
