Code 26, air / fuel ratio rich malfunction Options

[Bigmeanbulldog55]

I've been getting a code26 from my car. That's the rich air/fuel mixture code. I know, the 5sfe runs rich anyway, but not enough to throw a code. I know my EGR is needed cleaned. I also know that I welded close to my O2 sensor not too long ago. To stop the CEL, I unplug the O2 sensor and reset the ECU. This works, but I know it's not right. I was thinking it was either the O2 or the EGR, but when I look in the Haynes manual, it's saying: injector circuit, injector, air flow meter, cold start injector, or ECM. Anyone have any advice for me?

Which sensor did you work near? If it was the rear then no problem. I would try cleaning the EGR out and then see. Also I wouldn't worry much about damaging the sensor it would be more likely the ECU.

There is only one sensor on the 94 GT's, outside of Cali. It's the one in the exhaust manifold. I was welding on my header and I left the o2 sensor in while I was doing that. How could it be my ECU? I figured and ECU would just crap itself, or stay working fine, one or the other.
