High Pitch Whistling!
So I have a 95 Z28 and there is a high pitch whistling coming from under the hood... It doesnt happen all the time but often and when it occurs it screws up my idle making the car drop under 500 in most cases. I was reving it the other day while looking under the hood and u can hear it a lot after you do that. It seems to be coming from the right side of the engine towards the bottom. Anyone know what this can possibly be its pissing me off haha
