It could cause a misfire, but the alternator should have maintained enough voltage to avoid that from happening. Make sure the alternator is maintaining the battery. With the car running, it should be around 14 volts.

Seems like you could have 2 different issues here? But which cylinder is the one misfiring? Ignition coils are very common to fail on these vehicles.
