Uhh....im kind of stumped on this one guys. None of my friends or i can figure out what the noise is but its like a shearing noise like as if someone is rubbing sand paper together or something is loose and grinding very lightly.

It only does it when i accelerate and left off the throttle to shift or slow down.

I thought maybe its a vacuum leak or something but it doesnt do it when im sitting still and revving the engine. It only does it when im moving or in motion.

Its not dragging my car down cuz all the power is still there but im just curious. Ill try to post a video later on today with the go pro to see if you guys can hear it.

Any ideas or suggestions???

 

Anyone???????

 

I'm gonna go ahead and say heat shield rattle
mine does the same, did till I took those shields out
