This truck was running hot so I put a new radiator and thermostat in it. The Check engine light indicated that 2 and 6 was misfiring so I put new plugs and wires and new intake gaskets. The Check engine light went out. Drove it for 1 and 1/2 weeks and the light is back on saying 2 and 6 has misfire. What Could be going on now?Do you think when it was running hot that the head gasket needs to be replaced or could it be the valves?
