The vibration issue has been sorted
Ive been at the point of nearly giving up over the last few months but i got an email reminder for the insurance due at the end of this month and also due for an MOT test and road tax so that brought everything into sharp focus - So i thought id better get it sorted once and for all.
I took out the front es poly mount and fitted a brand new aftermarket (OEM Style) front mount which reduced the vibration quite a bit and then set the base idle using the guide in the wiki - but rather than set the idle to spec i set the idle where there was no vibration - it was easy to do and has made a world of difference to the running of the car.
The front mount is a copy of the OEM mount and is made by YAMATO pt no.154099YMT I got it on ebay for just over £30

Looks to be a well made part but i will be checking it for wear once a week.
Just need to wire up the fog light and it should be ready to present for MOT.
