I have 103,500 miles on my 6.0 3 ltr ranger. After a long drive my engine started to rumble, shaking the whole truck while sitting in idle at a red light. then the check engine light went on, i checked the wires and spark plug to see if i was getting good consistent spark and i was. Im thinking(hoping) its the fuel injector. maybe its something else and hopefully not a blown valve.
thanks for the help
