94 Corolla DX Sedan makes slight screeching noises when idle

[jinster]

Hi, I have recently bought a 94 Corolla DX with about 129,000 miles on it. Everything runs very smoothly except for a screeching sound when the car is idle. When I am accelerating or breaking it does not make this sound, but if I am coasting or sitting at a red light the sound will return. The previous owner said that they recently got a new timing belt, and thought that the sound could be from low power steering fluid. I've replaced the fluid but the sound remains.

Any help would be greatly appreciated.

Have you checked your belts?
