This code has nothing to do with the miss. what you have is a misfire. These distributor have the famous reluctor problem where the reluctor in the distributor tends to shift out of place and as you accelerate it misses like mad. Check the distributor ,this tang tends to shift out of place. if you have a misfire through the intake replace the distributor.
