Ok I've been having a CEL and to my knowledge it was for a an o2 sensor, but I have taken care of that poblem. Well the light came back, so I stopped by the parts store and had them read the code, and it was code P0507. Which turned out to something about the idle being high. The only other time I had that code was when I installed the e-manage. But then I had to put a resistor on the maf line, with a ground on it too, and that got rid the CEL. But now I am back to just the ECU. Anyone have an idea on why I'm getting this light?

Thanks
