Great Wall Jiayu v80 fault code p0300 is on fire, what does it mean?

Hello, dear! 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. (7) Gasoline pressure. Failure of electric gasoline pump, blocked gasoline filter or failure of gasoline pressure regulator lead to inappropriate gasoline pressure, resulting in too lean mixture. (8) Fuel injector. Dirty and stuck fuel injectors lead to poor fuel atomization; O-ring seal of injector is damaged; Poor control circuit of injector leads to long-term injection or non-injection of injector. (9) The harness is damaged. (10) The terminal connection is poor. Check the wire connector terminals for looseness, mismatch, locking damage and incorrect shape. (1 1)ECU is damaged, and the engine grounding connection is unreliable and unclean. (12) The performance of transaxle clutch is poor. (13) There are impurities in the fuel. I hope my answer can help you, please set it as the best answer! thank you
