   As far as I know, the Durango has never had the plugs replaced.  Still runs   
   perfect.  It has 135k on it now.  My Monte Carlo just went over 156k.     
      
   It would be nice if I could figure out a solution for the 20 second cold start   
   tapping.  Everyone has said not to worry about it.  I put sythentic in it and   
   it has helped alittle, but still does it for under a minute on those cold   
   mornings.
