chirping noise - NOW WITH VIDEO
All
If anyone can give me any indication of what this noise is...I would appreciate it.
Toward the end of video - it will become more pronounced This is when I was in any gear -with low RPM and then hit the gas. THis video was me in 4th gear going 40 and then hitting gas up to 45 mph or around that. It happens in all the gears though. Getting worse from when I first posted. Thanks for listening and any help you can shed. Make sure to have your speakers up a little...

Do you have to drive it or does it do it when it sits and you hit the throttle too... could be a loose plug (yes they make that kind of noise) or you have a pulley/bearing that's chirps.
Checking the plugs is a bit of a pain because you have to pull the coils out, but I'd check that... if they're all tight, take the belt off and see if its gone... careful though dont run it too long the water pump is on the belt...

It only seems to happen under load. When sitting idle and revving, no noise...

Quick way to eliminate anything running on the belt is pop the belt and take her up and down the road for a min... if no chirp then you know its a pump, idler etc. If it still does it check the plugs....
Dont worry you wont cook anything, just dont forget the power brakes and power steering wont work either so careful!

Well, figured it out and it is fixed. It was the new exhaust rubbing on the aluminum coating on the back bumper. The fabspeed exhaust is a little bigger so they did not cut enough of the pieces on the car away. Took it to the installer, they trimmed a little more off the edges of the fender lining and aluminum cover and it is now perfect. Thank god...it was driving me nucking futs.
