Dennis,
When you check the coils with the coil disable function on runup, is there enough of a change that you would expect to notice one plug intermittently not firing in cruise?

Mark - You are not alone with your occasional intermittent misfire. I also have the miss as you described - I only notice it in cruise. It happens once every 15 to 30 minutes! I wonder if it is one plug not firing instead of a complete miss of the cylinder. I'm using the Renesis RX-8 coils and RX-8 Iridium plugs with Tracy's EC-2. Most of the time I use mogas.
