December 2, 200817 yr 1996 Legacy 2.2 Can these be bad and not throw a code? Im hearing a pinging noise and not sure if its timing related or a shield rattle..sounds more like a ping, though I hear it only over 35 mph,with a light throttle.Nothing under load and i also hear it under deceleration..cant believe it would ping then..any thoughts?

That's heat shield for sure. Pinging wouldn't happen under deceleration, or at light throttle, it'd be during heavy throttle and load.
