Q: engine missing on 2003 Mercedes-Benz CLK500

I mistakenly put 89 octane gas in. Now the engine occasionally misses and sometimes stalls. I have refilled the tank with 93 octane gas. Will this correct the problem,or is there more I should do?

Is should correct itself because the computer has to adjust the knock sensor to make up for the lower octane fuel so it might take a tank or two
