    95T running too rich, no ECU codes

    UPDATE: Finaly got a code that makes sense out of the ECU besides the engine misfire ones. Code 64 is indicating that rear secondary O2 sensor has a problem and is not working. Would that make the car run erratic power cold and put the car in failsafe or limp mode? The exhaust is very black too...
