Is a loose spark plug sound easy to hear?
I have this mild clicking sound that I hear when I gas it next to a highway median, next to a wall, etc...Like a playing card in bicycle spokes.
It does not make the sound at idle or when I rev it up in park. Nor can I hear it at WOT since the blower and exhaust drown everything out. I can't hear it a mild throttle without a wall next to me either. I can only hear it when the sound bounces off a wall/median at mild throttle.
I know this could be a number of things, but I have no idea how loud an exhaust leak, slipping plug, detonation, etc.... should be. The truck has a good safe tune on it, so I wouldn't think detonation unless someone says differently.
