Car has a little over 50,000 miles.
Whenever I accelerate and even let off the gas pedal, there seems to be a whine that follows the car (almost like an R/C car). It goes with the engine almost.
Also when I shift my car into 3rd gear (its a manual), after about 2.5 RPM, I hear a high pitched sound that continues with acceleration, but stops when I let off the accelerator.
Any clues to what may be causing these problems? I just got the car and there seems to be nothing wrong with it, got it checked out with a mechanic and everything.
