Proud owner of a96 discovery rust bucket. Owned for 2 yrs it rattlesmoans and groans but keeps going. I found it easy ish to fix. But has started to overheat (notfully investigsted yet ) as at the same time when going up a hill or small gradiant on the motorway i suddenly have no acceleration, like there being a limiter fitted. So not sure if this is due to overheating with it having an auto box. Any ideas ?. Thanks
