The other day I noticed it sounded like birds were chirping under my hood. Naturally, I thought a belt or pulley. The belt was brand new but I tried dressing anyway and it didn't change at all. While doing this I put my hand on the distributor and noticed the chirp changed. By moving the cap it makes the squeak change. Now I figured at least I had found the location of the problem and could start from there. I went straight to the auto part store and changed the cap and rotor even though they weren't that old. To my dismay the chirp didn't go away. Anybody have any idea what it could be? It seems to do it more and louder when it's cold and normally goes away once the car warms up. The problem is it will do it even when hot sometimes too though. Any ideas or help would be greatly appreciated.
