i have a big turbo escort when started from cold it runs perectly clean no smoke at all and the same when hot but sometimes when driving say at 1800 to 2000 rpm and i accelerate it puffs some smoke not blue more of a blacky colour if i stop at side of road nothing i have smelt the smoke and it does not smell oily it also does it if i have been coasting down hill at the above rpms and accelerate it does not do it when it is boosting well any ideas please

Black smoke is usually a sign of over-fuelling.
