I took out my plugs the other day and they were half black and half brown?It looked like half the plug was firing properly and have was burning lean.Anyone else see this before?It was on the lower 2 plugs I saw this more than the top ones.

My plugs have about 3200 kms on them.They can't be toast yet could they?

3200 Kilometers equals 1988.39 Miles (statute)
