Your problem may be a vct solenoid sticking open intermittently. Defective wiring controlling the solenoid could also be an issue.
If your Alternator went full voltage output I guess anything can happen however sensors rarely go bad especially two of the same at the same time. MAF sensors can fail but most I know of had only needed a spray cleaning with MAF Sensor Cleaner and allowed to fully dry before reinstalling. MAF Sensors may cause driveability problems if over oiled gauze air filters are used and the oil gets on the sensor. O2 sensors aren't adjustable although I've read of people trying to raise them out of the exhaust stream to fool the pcm if I remember correctly.
I had a vct solenoid that was allowing oil to seep into the connector area on my 05 but it hadn't caused any problems. Good Luck.
