While driving i noticed 2 things.. First, sometimes when i go throught a dip, very slowly ofcourse... i get this strange vibration on the brake, and strange noise... (only happend twice since i got it) Second, sometimes when i shift from 2nd to 3rd, mostly over 3000 rpm, my stick begins to vibrate allot... This could be a noob question, but i just got the car, and i am sooo paranoid...
