Could be something in the exhaust? Vacuum leak? Power steer pump? Hard to diagnose by a second-hand description.

if it's doing it at idle, you can tip a bit of water on the belt and see if it goes away... might be the belt only

A blocked BTR auto trans filter, can also make a whistling noise on acceleration -

the transmission oil pump becomes noisy like that, as it strains to move fluid around.
