The P0300 and P0304 codes in a 2003 Ford Ranger indicate random/multiple cylinder misfires and a specific misfire in cylinder 4, respectively. Common causes include faulty spark plugs or ignition coils, fuel delivery issues such as clogged injectors, vacuum leaks, or engine compression problems. Additionally, sensor malfunctions, like a malfunctioning mass airflow sensor or a faulty camshaft position sensor, can contribute to misfires. Proper diagnostics, including checking ignition components and fuel system integrity, is essential to pinpoint the exact issue.
