it could have been running bad with the bad plugs. reset the computer and see if the light comes back on. you may have already fixed it. to reset the computer take the positive cable from the car off the battery and give it 3-5min to discharge then touch the positive cable from the car to the negative cable (still attached to the battery) for about 5 seconds and then hook back up the positive post and that will reset the computer.

SOURCE: 02 sensors
the printout from Auto zone tells you that there is a probelm with fuel mixture control, this doesn't always mean the O2 sensors are defective, intake leaks and iother factors can give O2 codes, give me the code you have and i will let you know the most likely problem.

The code will tell you which O2 sensor it is.
The code will point to either bank 1 sensor 1; bank 1 sensor 2; bank 2 sensor 1; bank 2 sensor 2.
From what I remember with a focus, it should only have 2 sensors, sensor 1 will be located before the cat, and sensor 2 will be located after the cat.

vacuum leak in PVC line or clogged PVC. its a leak after the map sensor. o2 sensor is correcting for a lean condition so its adding fuel to your car when the o2 sensor detects the extra air.
