tach acting funny??

For some reason today i noticed that the tach is acting funny. There is also a sqeeking sound coming from under the hood. Maybe one of the pulleys or something. But my tach seems to be extra sensitive. Also when idleing the tach sits at 1100 rpms instead of 600. The truck is idleing normal.
any ideas??
