You need a special tool when they are stuck on, it's like a long pair of neddle noise plyers with sides that grabs the wire by the boot evenly, but twist them loose from the plug as you pull the rubber actuaully melts itself to the plug sometimes

uhm to my knowledge there is no alternator fuse, but i could be wrong. usually those just go and you get an alert in your cluster that looks like a battery and it stays on that means the alternator is fried and jsut get a new one, the alternator has a wire goin straight from it that goes into the battery to charge it there is no fuse that i now of

P0037 - O2 Oxygen Sensor Circuit High Voltage (Bank1, Sensor2)
The Heated Oxygen Sensor (2) located rear of catalytic converter produces an output signal relative to oxygen storage capacity of catalytic converter. Ho2S 2 signal is less active than signal produced by front oxygen sensor. This code sets when HO2 Sensor voltage is greater than 999 mV for more than 2 minutes (time depends on model. Could be as high as 4 minutes)
Symptoms: There may be no noticeable symptoms except for MIL illumination. Possible high fuel pressure can over rich the system.
Causes: A code P0138 may mean that one or more of the following has happened:
* Faulty O2 sensor
* Short to battery voltage in O2 sensor signal circuit
* High fuel pressure (not as likely)
Here are some potential solutions:
* Replace O2 sensor
* Repair short to battery voltage in o2 sensor signal circuit
If you replaced the O2 sensor, then its possible that you have some electrical problem there; reset the codes first, and if this come on again, check in this link TSB P0037 electrical diagnostic procedure.
Keep us updated.

check spark plug of the cyl. switch plug with another cyl, run engine until warm to see if misfire still comes on. if it stays on the same cyl. fault could be high tension wire or coil or worse leaky valve or rings. if misfire switched to the other cyl just change plug or better replace all plugs
