Replaced plugs last week with NGK ILFR7H. Today I got misfires in cylinder 2 and 4. Went to pull the plug in cylinder 2 and the metal piece that you bend to adjust gap width is gone. It must still be in the engine. What do I do? I haven't pulled the plug out of cylinder 4 yet but I'm praying its not broken off too. Am I fucked? Should I take the whole engine apart to look for it? I don't think I have the skill for that. Should I just replace the plug and forget it? I'm trying to fish it out with a magnet right now. FML I can't believe this is happening...
