Humm, give it some time. there are upper cylinder cleaners, but I worry about converter damage, and oxygen sensor damage. The lower the octane, the hotter and more masssive the burn, exactly backwards from what you would think, but higher octane is slower burn and av.gas is really, really slow.
\012Ford has had slow to start issues that traced back to drivers using too high octane....

\012Still, if it keeps pinging, you may need to run higher than spec octane.
\012I would have thought that your car would have knock sensor that would trim this issue...
