I have a 2003 ford focus zx3 2.3 litre motor,coil on plugs.It has been cutting out when you turn on the AC,turn it off and it is fine.I went and had it scanned today and the codes were a P03102 and that was a misfire on cylinder 2.Then it had a P2274 and that is was a oxygen sensor stuck or something,then it had a P1299 and that didn't have what it was.And my manual that I have does not have the same numbers all the numbers it has arePO then 3 numbers and they all are PO.So the two the P1299 and the P2274 are confusing me.And why would a trouble code have the number only not the sensor?So if anybody has any information on these codes I would appreciate it.

1299 means it overheated at one point and there is no 2274 only 2273 which means O2 could have becom e wet with fluid contamination on wires or a shorted wires, etc.

OK now with the P0302 Misfire cylinder 2 could that make the 02 Sensor Stuck Lean have something to do with it.Like I said it only misfires when AC is on when there is a load on it?
