LOL steviej! I can't help it.....just the way I am....dealers even look at me funny the odd time But hey, I'm paying for the maintenance so I'm not all that concerned what the dealerships think, their our cars right? :D
99ls, there is a tool that you can use that measures different spark plug gaps & also to adjust the gaps (can't remember what the damn thing is called right now ) But the new plugs that are specifically for a certain car usually never need adjustment, but you can get the tool to double check the gap if you wanted to make sure it's correct. I'd probobly do that........ ;)
