Ssanguong Musso 320: Only at idling, which is running low, black smoke is coming from exaust with rich fuel smell. Had the car checked on computer at 2 differerent places and both computer checks shos no trouble codes. Is the problem the air flow sensor? The reading on this sensor was 12.4. Can it be the fuel regulator or what? During normal drive the car has enough power and no smoke. Uses a lot of fuel.
