I have a slight vib/rattle to the right of center dash. It only does it just coming off idle and only when it's first started. After about 3 to 5 minutes it goes away. Idle no rattle, light throttle input rattle, RPM goes above 1000 and it's goes away. I don't get the vibration on deceleration passing said RPM range only when accelerating. Makes me wonder if it's exhaust related and once heated tolerances change enough to make it go away.
