Hello, I have a 2010/GMC/Sierra 8 cylinder. I'm having a problem with this code and I've changed spark plugs fuel injector the coils and a MAF sensor and still having trouble getting my truck going. Smell like it's burning pour fuel. I'm just asking, if anyone has an idea. Appreciate it if someone could answer me ,thanks. A P0300 diagnostic code indicates a random or multiple cylinder misfire, often caused by spark plug failure, vacuum leaks, faulty ignition coils, or fuel delivery issues (e.g., low fuel pressure or clogged injectors). The issue signifies that the ECM cannot pinpoint a single cylinder, with worn spark plugs.
