Tell us why you think the plugs indicates a rich condition - photo if possible. If you are passing emission tests, I doubt if there is a problem.

Plugs will always accumulate deposits, typically black on the metal shell when running unleaded fuel. What really counts is the deposits/color of the porcelain insulator.
