I have just had the second sparkplug changed in my '03 Cruiser within about 2 months. Different cylinders, non-turbo engine. Has anyone else had this problem? Are they using crappier plugs? I had no trouble at all with my '01 Cruiser for the 50K or so miles I had it. This one just passed 10K ! The dealer was good and fast about changing them , but I don't really want to go back every coupla months to get a new plug... They just told me that plugs are like light bulbs: sometimes you simply get a bad one. ****************************** Got wood?
