Hello Everyone . I uploaded 2 videos . You can hear from the one under the hood . I have this flapping noise and its making the car idle really bad . You can also hear it from the exhaust .It sounds raspy then it goes away and comes back . Any ideas?

Thank you

 

No one seen this before ?

 

Just listening to the exhaust video it sounds as if the sound is originating in the exhaust. Have you checked the pipe connections? Or if there is something lodged in th3e pipe/s.
Is there a noticeable difference in the driving?

 

No the exhaust is clear . The car idles weird . But the thing that's worrying me is that flapping noise under the hood . it sounds like the flap on the throttle body is loose .
