In the mornings when my car hasn't been driven from the previous day, I start my car, and this annoying noise comes upon. It sounds like a screeching noise. Also, the idle on my RPM when the car is started is at around 1200. When i put it in drive the car goes back to its regular rpm state. Also, the noise comes when i accelerate a little and goes away after a while. Does anyone know what this might be?
