My 2002 Deville has started making a whining noise when accelerating after about 35 mph. When decelerating it winds down and then stops.

check manifold gaskets for leaks, check vacuum hoses for leaks. check the transmission oil condition ( auto tranny)
if it is an auto then it may require the pan to come off and check for mechanical fault.

Could be a bad computer not supplying right fuel injector pulses. This happened to my 1990 cadillac deville at about 35 mph, it would buck and miss.
Also, I would flush the coolant system and install new coolant.
