Thanks Ben,
for the reply and help.

Would you not expect some scaling of failure into the 50/15 test
considering the severity of failure in the 25/25 test ?

After researching some , would you expect a Oxygen Sensor
malfunction or something else ?

Can the original O2 sensor last 18 yrs ? The O2 sensor is the
original :}

Thanks again,
