I bought the truck about 6 months ago 4100 and was running good next thing u know I started having electrical problems it was a old state trooper car I changed all the sensors and spark plugs and still the code reader spits off bull shit..the only thing I think it could be is the ecm brain 200 dollar fix ..just I'm over this truck..starts and runs just goes into limp mode when it wants...nice truck black on black..
