[Shotimes] Oxygen Sensor Question

[Kevin & Cheryl Airth]

Barry:
 Clear all the codes first and see what comes back. The O2 code can be set
by oil in the plug wells. Since the rear bank is harder to get to some
service people ignore it! I have had repeated O2 sensor codes from oil in
the plug wells.
On the MTX changing the O2 sensors is not too bad.
 How old are the wires and plugs?
