i recently just got a 05 6mt, and learned how to drive myself. ive been putting it in neutral when going to a red light. then when waiting at the light i put it in first and ease off the cutch until i get to the 'sweet spot'. now my car makes a weeird noise in first and second at low speeds. do you know what this could be? and at red lights should i leave it in neutral until right before i take off?
