2003 GMC Sierra (Classic) 2500 HD Crew Cab · Truck · Driven 90,500 miles

Basically a 1 owner super low mileage and all stock truck. It is an lb7 duramax with 90,500 miles. Previous owner had new injectors installed, but one of them is essentially stuck open. I haven't been able to dig too much into it. I have the original paperwork from when the truck was bought in 2003! NEED GONE ASAP. Moving soon and don't have the room to take it with. $7500
