A friend of mine that has an 04 v6 said every time she starts up her car it makes a wierd growl like noise. It only gets worse when she turns on like the ac or heat. And its worse when the car sits for a while(like startin it in the mornin). It only lasts for a few miles and then goes away, and it doesnt vibrate or shake, just makes the noise. She has intake and exhaust, but i dont think thats got anything to do with it. And the growl comes from the engine bay not the exhaust. She said she took it to ford and they claimed it was cause she "modified her engine". Anybody heard of this before?
