strange whistling noise from under the hood when temperature is around zero degrees and colder (celsius) appears only when vehicle is under load if you let off on gas noise goes away also when you put your foot into it.strange thing is when cruise control is activated no sound and cruise works better nice smooth acceleration under load and it doesnt constantly hammer down to a lower gear to maintain the set speed like it used to.as i said it accelerates smoothly. so what is it a throttle problem ,transmission or valve or vacum leak of some sort.... help and thanks.
