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...
