spark plugs
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.
