I hear a grinding noise coming from the alternator area. Sounds like this http://www.youtube.com/watch?v=1uvW18xeGCw

The noise gets quieter when driving.

Get a cheap stethoscope from harbor freight and check the idler pulley and alternator. I had to change one on my 99 GT.

probably the idler pulley. bearing might be going out or something in the pulley.

IIRC thats the same noise i had when mine went bad.

When you hold the stethoscope on the part that is bad you will hear it otherwise it will be hit and miss trying to narrow it down. I guess you can use a screwdriver also.
