Out of the blue, the engine makes a squeal when accelerating while engine is still cold. Sound kinda like a banshee passing a kidney stone, and it progressively gets louder the more you press the pedal. When you let off the pedal it lets out a sharp squeak. This little game lasts until the engine gets warm. I've changed the normal line-up, water pump, idler pulley, tensioner pulley, a/c compressor, serpentine belt, fuel pump, etc. Was heading towards the power steering pump next but thought I'd ask around first. It doesn't affect performance but is annoying as @$#!. Thank you.
