Lude Generation

Could anyone shed some light on this please, ticking over cold, hunting. Ticking over hot, hunting, but sometimes it stops hunting, but not very offten

Try cleaning idle control valve out first . Could also be an air leak .

check the FITV as well- once the car is up to temp then take off the air intake pipe and put your finger over the lower port inside the throttle body - if there is vaccum when up to temp then fitv is faulty/needs cleaned and then reseated(also worth checking the orings and cleaning up any corrosion between fitv and tb)- there should be vaccum there from cold but as the temp rises the valve closes and no vaccum should be present if thats all ok then it could be iacv - again take it off and blast it clean with some carb cleaner. Also worth bleeding any air out of the coolant system.

Yep those, plus could be a clogged/faulty fast idle valve or air trapped in the coolant system

Thanks for the response, is there any chance somebody could post some pictures to point me in the right area

When my lude ran seriously low on cooling fluid, it started hunting.
But if you didn't have a huge gushing leak like me, or a persistent small one, then look elsewhere.

yeah ive just reset the fast idle thermo valve on my BB1 - hunting has totally gone and car feels so much better but must have screwed it down a bit too much as it doesnt operate from a cold start - overly fast idle has gone down from 2000rpm to about 1000rpm which is preferable imo- so i would say dont adjust the screw in cap down too tight although i did back it off a turn.
