2000 Dodge Durango 4.7L Excessive Emissions, Poor Fuel Economy, MIL Lamp on
O2 sensor full of black soot, non responsive, for the second time in 500 miles. Running full rich. Appears to be seeping oil out of the top of the sensor. Do the 4.7 motors have a problem fouling the O2 sensor? There are no vacuum leaks that we can find.
