I will check for vacuum leaks. The problem isnt the rotors. I just replaced front rotors and the axle and the bearing. So its not that.
Yeah if the heat is on and i come to a red light the car just vibrates alot. IF I turn the heat off for a min it will stop for a SHORT time and vibrate to hell again. Its very annoying.
