i have a 2000 ranger, 4.0, 4x4, manual, everything runs fine and no engine issues but i have replaced the same oxygen sensor 3 times in about a two year period. any ideas what might cause this thing to keep going bad. after i replace it i will get about 300 or so miles out of it and then the light comes on...i get the codes read out and every time it is the same sensor.
