did it only occur under light throttle? I wonder if the vacuum leak from the intake manifold would result in leaner (more engine ping) condition under more load?

The amount of air that leaks is dependent on the difference in pressure (delta P) between manifold and ambient. Delta P is lowest at WOT, so the least leakage occurs.
