po1153 code I have slp long tubes and set this code every now and then.
Usually when idling or on initial warm up.Replaced both front o2's which cured the problem for a week.I have inspected the wiring and found no defects.Any one have a fix?

Re: po1153 code What kind of wiring extensions (if any) are you using?
P1153 is passenger's side, insufficient switching on front O2 sensor. Could be an exhaust leak, bad O2, or bad wire.
