How many miles? High mileage engines often require more octane to prevent pinging or even worse knocking. Did you have the fuel injectors professionally cleaned or simply add some fuel injector cleaner to your fuel system? If it were my car the first thing I would try is adding a bottle of Chevron Techron complete fuel system cleaner to a tank of 93 octane premium. If that doesn’t work you could try an octane booster.
