Causes of a P0305 Code: Cylinder 5 Misfire Detected

An engine misfire is when a cylinder has an incomplete combustion ignition or has no combustion in the cylinder. Each cylinder needs the correct air-fuel mixture and Spark at the right time to complete combustion. If the vehicle only has a P0305 Code, then the individual components on that cylinder should be tested. A cylinder's individual components would include the coil, injector, spark plug, and spark plug wire. If there are other engine codes, then there may be other issues. For example, multiple misfire codes (P0300, P0301, P0302) can be caused by low fuel pressure, bad sensors, vacuum leak, and more.
