Did my plugs and injectors over the weekend. I think plugs were redone sometime by the previous owner, but the injectors were all original. Also wet sanded and polished the tips on the mufflers. Injectors have 28k miles on them. Just thought I'd share pictures of them at 11yo/28k mi
That could definitely work depending on how much carbon has built up. I tried 2k and 1k grit wet sanding but I needed a little more cutting to get through mine.
