Right, my t2 has started to feel really sluggish all of a sudden. It stills revs however just doesn't seem to go anywhere at all. It used to be pretty nippy up to about 60ish however it now struggles to get up hills in 3rd. Anyone got any ideas???? I know it needs a oil change and new fuel filter which I have. The T2 also had a slight waterpump leak (I have a new one but haven't fitted yet).
