2003 DURAMAX LB7 engine.
So I was cruising on the freeway last night and noticed black smoke out of my passenger mirror, along with a hesitation in the engine. I got off a ramp and stopped and the engine is making a knocking noise and spitting black smoke out of the pipe. The truck had the injectors replaced about 15,000 miles ago. The truck has great oil pressure, coolant temps, and everything else. There is also NO CHECK ENGINE LIGHT. Weird.
Anyone know what it could be? Does anyone have access to a Tech 2 or computer to read whats going on?
Any help would be greatly appreciated.
