XJ (X350, X358) Aluminium Body 2003 - 2009
My 2003 X350 4.2 not supercharged, 240K km, has a problem: revs are sometimes fluctuating / hunting. It is noticeable on the rev meter and feels like my granny is driving.
I saw the topic on that problem, but mine seems different in that is also happens after 30 minutes or more, when at least...
