I have a 2003 Ford Focus zx3 2.3 Litre motor.I have been having a misfire code PO302 cylinder 2. It is a unusual problem because it cuts out when ac is turned on turn it off it is fine, but some times it will cut out without ac running. But I have a another DTC number, well we had Pep Boys scan it and it came up with P2274, and I think it suppose to be P127, 02 Sensor Signal Stuck Lean-Bank 1 Sensor 3.I understand the bank one front of motor, but where is Sensor 3 located. And does anybody out there know how to test them. Thanks
have the same problem?
