Changed my spark plugs and one was REALLY bad!

An exhaust leak after the O2 sensors will not affect how the engine runs. But a leak before the O2 sensors will cause it to run rich. So will misfires.... and it had to be misfiring pretty badly with a plug that looks like that. Could also be a faulty O2 sensor, or faulty O2 sensor wiring.
How many miles on those plugs? Look like the originals from the factory.
