Yup, I suspect SAG.  I go through plugs very quickly..  like 25hrs.  No
cleaning will help as the electrode is worn out.  You can milk them to 100
hrs but its not really worth it.  SAG gets really bad by 75 hrs.  The
platinum onea last an extra hour or two.  Have not tried the iridium.
Always change plugs before a long trip.  Also, they come out much easier
after only 25 or so hours.
