I have a very clean international prostar, with maxforce engine. Truck is very clean 4 new drives, 2 new steer tires, and 4 like new drives. 2 new turbos, fresh service. I bought the truck, drove it 3 time back and forth to columbus and this morning it running rough. I do know check engine light is throwing number 2 injector. It starts, runs drives, but blowing black smoke when you gas hard on it, and spits and sputtering. I know it's a injector. Nobody in town will work on it. Im not even gonna mess with it. Oh it also has full delete.
