1990 Mazda B2200 Q&A
1990 Mazda B2200 Question: Replaced O2 sensor for a bosch new one. Since then i've got check engine light.
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. - juancarloslax
