    Auto repair
    I have honda civic 2000 lx. I had a check engine light on, so two months ago I replaced exhaust manifold, converter, and O2 sensor. Check engine light went away. It is back after 4000 miles. I did not change the second O2 sensor which is down in the converter. What could be the problem?
    Thanks
