I have a problem. I have a 2005 Duramax LLY with almost 50,000 mi. Over the past two months, I have noticed at idle it has a rough, off balanced idle. Not sure how else to explain. I have been running the Ultra Low Sulfur Diesel because that's all you get around here. Also have been using AMSOIL's Diesel Fuel Concentrate. Could I be in the beginning stages of injector issues? I have noticed also at times when I start the D-Max, it doesn't kick right off and has to turn over several revs. The injector harness was replaced because it fouled up but that's all I have done other than maintenance (air filter, fuel, transmission, oil, etc) Anyone have any suggestions as to what to look for? Truck runs fine on the road. Haven't noticed too much additional smoke than would probably be normal. HELP!
