Hello everyone.

I have a automatic 2005 civic with 200k miles and maintenance has been kept with the car.

Recently I've had this noise that has been driving me crazy.

It only does it when accelerating slowly on low rpm. For example when I accelerate and then the gear changes and I hold it on low rpm is when I hear this noise. Around 2000 rpm, If I let go it goes away and if I accelerate more aggressively it also goes away.

I have checked for any lose bolts and heat shield and everything is in good condition.

Here is a video of my phone recording under the hood when I went for a test drive.

Thank you in advance for any feedback.
