hi all,
i drive a B310..

when i start the engine in the morning and it is cold (i take off the auto-choke already),
for 2 minutes or more, it is shaking very hard, and sound like boxer engine.. the sound, hard to drive.

when the engine is warmed up,
it is smooth
but even in idel, or when in low speed,
i can feel vibration (feels like vibration from your mobile phone, but more rough).
i can feel it from the steering, gear knob, even the car not moving.

when travelling around 110kph (speed limit on some road), the vibration is quite large.

yesterday i travelling at 140kph, the whole car vibrate as if it wants to fall apart,
and with a lot of sounds...


anyone knows what cause the problem?
is it somewhere in the clutch assembly?
or engine mounting rubber?


thanks in advnace
