I have the day off today so i finally got around to replacing my oxygen sensor this morning (day off and still up at 5:30 thanks to my 2 year old). I meant to do it with all my other work last month but forgot to.
anyways, here's the old sensor:

I can't imagine im running THAT lean after the last mixture adjustment so im assuming the white is due to the techron i put in after all the other work. at least that's what im going to tell myself
after the new one was installed i fired the car up and adjusted the dwell again as need be. its still not perfect (and i still have some metallic rattly noise under moderate to high load - not sure if pinging, so it might mean my injectors need a good cleaning (figure fuel lines are next on my list so while i'm there....)
here's the current reading with the latest adjustment after the oxygen sensor was replaced:
