Firstly welcome to the Forum.
The list could be long but the basics I have dealt with are:
AAV jammed, about 98% of V12's have this issue.
TPS setting out of idle fuel map range, age related, and common enough to mention.
The common Black Goo inside each throttle body, VERY common, and needs wiping out at each oil change.
Spark plugs are gapped wrongly, VERY common.
