Several lights such as check engine flashing , stabilitrak, traction control and rough idling came up all at once. After research I was quickly able to find that it was simply a problem with miss-fires in the cylinders and the other indicators were common byproducts. I simply changed the spark plugs and fixed the problem instantly. Truck runs great, I took it over a mountain pass and back pulling my camper immediately after with no problems in the 300+ miles over the weekend. Hope this helps:)
