would much appreciate some help/ideas have an ep82 which has started idling high, around 1500 rpm. also, its started to pump out smoke although i can't put my finger on exactly when it does this. it seems to a little when on boost, then as the engine slows down through a gear, it pumps out a big cloud when i press the accelarator again. it's kinda whitish blue, which doesn't really help!! had it in a garage who said all sensors are working fine and they got the idle down a little, but they don't really know what else to do next. there's a breather pipe that seems to be weeping a little oi
