This can lead to similar issues as mentioned before, including a rough-running engine, reduced power, decreased fuel efficiency, and increased emissions. The potential causes of a P0305 code are similar to those of the previous misfire codes and include: 1. Ignition System Issues: A faulty spark plug, ignition coil, ignition wire, or ignition control module related to cylinder 5 can cause misfires. 2.
