The old O2 sensor didnot give me check engine light.But the new one did it twice then turns off when I park re-star my truck again. Any advice what can I do ??? A friend of mine told me BOSCH works better with european car. He says I should get a nipondenso instead. I just changed the old O2 sensor cause black smoke problems.
