Oxygen sensor readings

[jamber2541]

Is it normal for the Oxygen sensor to read 83 mVolts and then jump up to 815 mVolts come back down to 92 mVolts and then go back up to 783 mVolts etc.

Yes, it's supposed to switch rich/lean, which is exactly what it's telling you by the voltage.

You have problems if it's stuck in one area.
