Vibration at idle

[Ska]

Yeah, that's right another vibration. Its not missing or hunting & very evident when cold and almost feels like a wobble, my first insticts are dodgy engine/ torque mounts but these are fairly new (replaced when I had the Diff. vibration). My second suspect is the vibration damper on the crank pulley, it started soon after the diff. problem but wasn't too noticable TBH its still livable but I want it fixed JIC it is this damper as it may upset my crank bearings etc. I think the excessive diff vibs have taken its toll on this; what do people think?
Simon Harper has experienced this when he popped over a while ago but this evening when I started the car to go home it was quite pronounced. The vibes decrease or disapear when you rev the engine and it doesn't make a difference if it's in gear or not.
Ian do you have a vib damper for a '97 ACK?
