I have a 1996 Ford ranger xlt 3.0 v6 . it keeps puttering out ,but only when fully warmed up . I have just flushed ,the radiator as well as reverse flushed,and changed the thermostat to a 192 degree one . that only prolonged its running time about 30 minutes before it has died again . I pulled the spark plugs and the #6 plug has oil all over it ,is this what's causing it to die after running for a while ?
