Jinbei sea lion fault light p0300?

Fault code p0300, indicating that engine misfire is detected. The fault code P0300 may include: (1) poor contact or excessive resistance of the ignition coil of the corresponding cylinder, and the ignition coil is damaged. (2) The cylinder line of the related cylinder leaks, breaks, the spark plug gap is too large or too small, or there is carbon deposition between the electrodes. (3) Air flow. The powertrain control module detects that the output of the MAF sensor is lower than the normal air flow, resulting in a lean mixture. (4) Air intake system. The air leaking into the air intake system bypasses the air flow sensor, causing the mixture to be diluted. Check the vacuum hose for disconnection or damage. (5) The crankcase ventilation valve is improperly installed or faulty, or the assembly surface of throttle body, exhaust gas recirculation valve and intake manifold leaks vacuum. (6) The 6)EGR valve is not working well, resulting in too thin mixture or too high exhaust gas recirculation flow.
