I own 2, 2013 accord lx's. One of them intermittently misfires, flashing engine light. Turn off car, less than 1min, restart, & trouble is gone, no codes etc, until it happens again... Has new plugs, and I swapped all the coils from one car to the other and still happening... Any ideas/help would be appreciated..

 

You have a flashing CEL and no codes. Is that correct?
