Our Hyundai Starex, have failed to climb a steep incline in our last out of town vacation. There was an incredible amount of black smoke coming out of the exhaust and it just failed to climb the inclined road. When road is plain level, there seems to be not too much of a problem but only on and off spewing of black smoke by the exhaust. What must be the problem?
