I have a second Gen 3sgte, still running the top mount, stock injectors, 3in dp and 3in mandrel exhaust.
the car will backfire on occasion, you could sometimes smell the unburnt fuel and my air fuel gauge reads well into the rich area. Any suggestions? thanks |

that gauge is good for one thing.. telling you if your o2 sensor is working correctly. at warm idle, or at a cruise, it should bounce around from lean to ritch. if it dosnt do this, and just reads ritch or lean then your problem is with the o2 sensor. replacing it with a new one would fix it.
