I am getting ready to do a spark plug change next week on my 03 Suburban 1500 5.3L I have had the vehicle since 66k miles. It now has about 130k miles. I have no clue when or if the plugs have ever been changed. Are there any known problems with removing these plugs that I should be prepared for and any tips or tricks to help make this go smoothly? I know the older Expeditions had issues in some of the years with plugs breaking and the head threads stripping, I just want to be prepared if there are any known problems on the Suburban.
