Spark plug condition and idle?

Understood. Enjoy the process....

If you look at the ground electrodes on your plugs you will find that 3 of them look worse. We have a wasted spark ignition and need Double platinum because half of our sparks go from center to ground and the other half go from ground to center. The wasted spark also uses up plug wires twice as fast.
