I hear a strange noise from the engine at low rpm as if it were Bearing . But I can't tell where it's from. https://m.youtube.com/watch?v=XU__hY1_WyA
YOU can copy the link and you Will hear it. I remove the SC belt and the noise is still there

 

Remove both belts. Spin all pulleys, tensioners, and supercharger snout by hand. Any roughness or noise means candidate for replacement.

 

I tried this, and the same thing again. It turned out to be the upper throttle body motor!
