wish I could, but easier said... anyway, I don't recall hearing it recently (I switched back over to 93 octane) but I'm not sure if that had anything to do with it or if the sound really went away (I can only hear it when I'm next to a wall and the sound bounces back). Could it have been pinging?!?!? I've never really heard pinging. I would say my car sounded like a pencil sharpener (not electric ) but quieter.Niss200SXGTR said:
