What!?
Resolve what? He doesn't even know what the issue is yet, lol!?
What was the root cause of your issue? Did you have a loose spark plug, or pre-detonation occurring?
I'm a little confused here, as just 'changing plugs' and using '93 oct' would resolve such an issue as rattling below the 3K RPM mark, especially without determining the root cause of the issue.
