Alright, so when I am accelerating and I get to about around 30MPH, from then on as long as I have my foot on the gas, the car (2000 Toyota Celica GT w/ 164k miles) makes a whine noise. If I take my foot off the gas pedal, the noise stops until I need to start accelerating again.

Any clue what this is? Could it be caused by an engine bearing? Anything serious you think, anyone have any similar experience?
