   Will do.  Depending on available time and the weather, I might work on that in   
   the near future.   
      
   RW> Too rich and too lean are the new-age way that is used to keep them in   
   RW> good shape for as long as they can still get a spark across the ever   
   RW> widening plug gap...consider the rest of the sensors that keep the ECM   
   RW> informed about how much air is passing through the throttle body, how   
   RW> much   
   RW> Oxygen remains in the exhaust gases, etc.. All of that info is used by   
   RW> the   
   RW> ECM to open the injectors and keep them open to regulate the air fuel   
   RW> ratio to make the engine run at its best efficiency.   
      
   Yes, all the sensors and ECM really provide the best life and efficiency to   
   the plugs.  Normally if one sensor doesn't work, you will get a code and   
   should fix it.  The only exception I have seen is the MAF - since that can get   
   "dirty" and still work.  Just not measuring the air flow properly.   
      
   RW> The big difference being that it has only one coil to fire 6 cyl.   
      
   True.
