P0300 Explained - Random/Multiple Cylinder Misfire Detected (Simple Fix)

The FIXD wireless OBD2 scanner and free app for iPhone and Android translates your check engine light into plain English so you can rest easy. In this video, we explain what OBD2 code P0300 means and possible causes.
P0300 means one or multiple random cylinders misfiring in your engine.
A misfire occurs when an insufficient amount of fuel is burned in a cylinder. The efficient burning of fuel is essential to engine operation as the combustion of fuel is what provides the energy to power the engine. A misfire from two or more cylinders can be caused by many reasons from a faulty ignition system, fuel system, or internal engine failure.
When P0300 occurs, it should be fixed immediately as long term driving with engine misfires could cause consequential damage to your engine and catalytic converter(s). Many times, P0300 occurs when there are worn out spark plugs, spark plug wires, or a faulty ignition coil.
