I have a quick qusetion. I replaced my plugs and o2 sensor today and was curious if they (my spark plugs) looked normal or not. They have a white dusting around the electrode with a dark brown area just on one side. I know that if there is a white flaky look to them then the car is lean and brownish black means rich but I'm not sure if this is right or not. Any insight would be great.

 

White haze is normal.

The dark brown spot is probably not a big deal.

 

That seems normal to me.

 

Cool thanks. I didn't know if the dark spots meant anything or not.
