my mum drive a vn 5Lt, recently it lost oil pressure and had to get the engin rebuilt. its going to be a bit hard to explain the problem because she doesnt let me drive it often and if i do i dont go slow enough for it to happen. when she drives through car parks at low speeds it hunts, only when idleing. if you let i go without excelerating the engin stalls, its auto not man if your thinking mabey she cant drive. theres no nods done to that i think would be affecting it, just cold air intake and hi-flo filter. if anyone has any insite that would be great because its not the safest thing...
It's probably the IAC valve, there's info around on the forums on how to clean it, or just buy a new one (it goes on the throttle body)
it could also have a missfire mine devloped one 3 days ago and it hunts at idle but at high speed (100-130) it vibrates like its going to fall apart. (why dose my car play up when im on holldays) its ok its fixed now
