Are you talking just the bosch tips or the whole injectors youre getting rid of? Might grab em if theyre cheap for spares, never have looked at the condition of mine, I think my timing might still be off too, I noticed yesterday and today with the driver window down that when I take off from a stop it pings like a gasser with predetonation, until it gets a little monentum going. Would that be considered "Nailing"?
