Rober V8 hunting

[DonkeyApple]

Not a TVR but in one of my 3.5 Rangies but as I had this issue with my Griff and no group knows these engines better than the TVR group I thought I'd post the question here.

Engine is on the Lucas flapper system and has suddenly started hunting on tickover. Not all the time but much of it.

Now, on my Griff it was the AFM but what are the other potential causes of this symptom?

Problem solved.

I took it to my Rangie specialist who pissed himself laughing.

I'd left the oil filler cap on the radiator.

I've wasted your time, my time and made myself look a right tit.
