2005 Pontiac Grand Prix 3.8 liter.
Question: We have a 2005 Pontiac Grand Prix GT
3800 series engine and the car makes a whirring
noise (Sound like a manual transmission in reverses) when accelerating from a stop. It first started only
when turning but now does it heading straight also.
Any ideas?

If the noise you are describing is related to engine speed, and not vehicle speed, then you may have low
power steering fluid, or another belt driven accessory making the noise.
Check the power steering fluid
level first.

If that is ok, then a belt idler pulley or alternator may be the culprit. Removing the belt and starting the car
for a few seconds will at least tell that it is drive belt related or not if the noise goes away.
