Glad to help
The knock sensor has to hear the knock and the O2 sensor info are compared then the injections respond with a longer or shorter pulse width (more or less fuel, think of a garden hose pistol more or less full on pulses)
Meanwhile the pinging has happened throughout the last 3-5 strokes.
New technology sees it at the per stroke. Oh and per cylinder. Ours only sees a bank not at the cylinder. Clogged injectors only make the issue worse. Add some Techron injector cleaner made by chevron if I remember correctly
