Miata 1.6 Coil pack problems, tips and fixes

He replaced the wires and plugs after I made the video. 2 of the plugs had their electrode burned down to nothing. Replaced plugs and wires and it ran perfect. His coil pack did have cracks as well. That has been swapped with the subject of this video. He says it runs better than it ever has and got over 32 mpg on his next tank.
