(Natural gas units)We usually look at coil voltage first.  If outputting high then replace a plug.  We check the quick and easy things first.  If still dropping out check bridge clearances and adjust valves.   We are currently dropping cylinders and looks like may be plugs(if gas units).  We are also approaching a maintenance interval so could be a combination of things.   Have noticed that the plug gaps get pretty large at a couple of thousand hours of running.
