I have recently bought a Daihatsu fourtrak (type F75RV-MBT), but have not had the opportunity to drive it for a while. This morning I had to move the beast, as it was blocking access in the garage. The engine started up quite ncely, but when I looked in the mirror to reverse out of the garage, my wife had disappeared in a cloud of smoke. The engine then ran very lumpily and deposited a small mound of soot on the floor. The smoke smelled very heavily of unburnt diesel. Is this sort of behaviour to be expected? Or, is it a symptom of dirty injectors, fuel filter, or, horror of horrors, something much worse?
Being an environmentally sensitive sort of chap, I would like to reduce emissions to the absolute minimum.
