ran out of gas this morning (deliberately, wanted to assess tank range to see what the "economy" was doing. I notice that the petrol isn't running smoothly at low-medium throttle. Flooring it and letting the revs go up over 3500 gets a reasonable degree of poke, considering the weight of a disco, but it's slightly rough at midrange and seems hesitant when asked to accelerate.
This is not new, in fact - when I first had it, it wan't that keen to accelerate, and if you feathered the throttle rather than flooring it, accelerated as well or better, from around 1500-2000 revs level - felt a bit like not enough fuel, but at higher revs it still pulled with larger throttle openings, so I don't suspect a restriction in the actual fuel supply.
any ideas?
