I'd say shiiit. I also had misfire symptoms at higher rpm before the distributor thing, and that was the cable going from the MSD box to the distributor. I made myself a shielded one ( a good shielded mains cable will do) and guided it along the firewall and the left engine compartment well away of the alternator. That did away with the most noticeable misfire. The rotor thing did away with the hesitation at cruising speed.
