Unlike a lot of the OBDII codes, this code has to do directly with engine combustion., P0305 is certainly a cause for concern, and should be considered a threat to the drivability your Blazer. The nice thing about P0305 is that it's a cylinder specific trouble code, which makes diagnosing the problems simpler than P0300, which means that the cylinders are randomly misfiring.. It will often be accompanied by codes P0301, P0302, P0303, P0304 etc…., P0316 Symptoms: Ford Ranger. When P0316 appears as a stand alone code, there isn't going to be much in the way of symptoms other than a rough and clunky start. The service engine soon light will come on. That's usually about it. When P0316 appears with other codes such as P0300, P0301, etc, it can be a symptom of a much larger problem.
