Once in a while, my car will make this weird resonance type of sound during idle. I have no clue on what it could be. I tried listening for it near the engine bay but couldn't hear anything. Only thing I do notice is my accelerator pedal vibrates very faintly simultaneously to the sound. What can this be?

Yepper, that's a weird sound.

I can't quite make it out in the video.

You say there is no sound in the engine compartment?

It honestly sounds a little like a bad A/C clutch bearing, but that'd be most audible under the hood.

Is there any sound coming from the exhaust? It's sounds kinda like an exhaust echo in the video.

Can you get the car in the air while it's running to see if you can at least pin-point the area where it's coming from?

Did you change anything on the car right b/f the sound showed up (had it to the shop, change a part or two)?

Keep us posted so we can try to help.

 

does kinda sound like an exhaust issue, check to see if anything is broken

 

raptors in the engine.....saw it on Jurassic Park last night

 

sounds kinda like a bearing of some sort. i had a 4th gen and i watched the water pump go over the course of a couple months and at one point it sounded like that if i remember correctly.any drops of coolant?

 

sounds like one of the pullys is vibrating. i had a bent pully, idk how.., but anyways thats wat it sounded like. or u got a mad wookie somewhere in the car...
