got this car about a week ago. it makes a squeaking noise i could not tell what it was. Today when i was about to put it in first i pushed the clutch alittle and it stopped. i took my foot all the way off and the noise came back. i also noticed the pedal shakes abit when im not touching it. want to take it back to ford dealer if something is wrong but want to know what is wrong when i go... any ideas. thanks
