I have a 1997 Chrysler Sebring with 120,000 miles. The car is my
daughter's and I just started to drive it. I noticed when I am on a
highway going greater than 45 mph, that when I step on the gas pedal I
hear a high pitched squeeling sound. The sound stops when I take my
foot of the gas pedal and gets louder the more I step on the pedal.

Any ideas?
