Unknown Noise When Idle

Anyone has any idea what's is this noise? I got this noise sometimes when idle, the noise is gone when driving.

Sounds like something vibrating. Like a metal vibration. If you bring up the idle while while its sitting in park does it go away as well?

No, it only goes away when driving. And it goes back when the car is not moving, whatever the gear mode is(P, N, R, D).

Can you take another video while someone slowly & slightly gives it some gas to increases the rpms as you do. Have an idea, but until I can hear if there is any change, don't want to guess

I went back & listened to your video a few times. Based on that & what you've said, my best guess is it's either the belt tensioner pulley or your AC comprise is starting to have issues. It's hard to make a diagnosis by listening to a video/audio recoding & I could be 100% off base. Good luck in tracking it down.

Here's another video I took:



Noise gone as soon as I step on gas. I'm taking it to dealer tomorrow.

Got it to work, I'm leaning towards the tensioner pulley. But again could by way off base.

FYI your engine sounds great, so I don't hear any problems there.

I appreciate your input, taking it to dealer tomorrow and I'll let them to figure out. Took me a while to take the VTC controller off my car in Phoenix's heat(120 degree today). In case they blame any problem on my after market mod.

I checked this video online, it's exactly the noise I have.
