340 Pinging using 94

It's doing it while decelerating now? Are you sure it's a ping and not a loud exhaust tick from a leak that you are hearing?

That’s exactly what I thought when I read that.

I can take a video.

For the "Vehicles don't ping decelerating", why is that? The engine is still firing while decelerating, it's just doing so at a lower RPM. And if the detonation is now occurring at a lower RPM after retarding the timing, I don't see how it's out of the question.

Now I could very well be wrong, and I am not using experience to justify my thoughts, just logic.

Engines don’t ping under deceleration because the cylinder pressure is way lower.
2 things can cause the fuel to fire off.
Heat and pressure.
This is why we are questioning that it’s actually pinging.
