Q: Getting error code P0304

P0304 means the engine computer has detected a severe misfire on cylinder 4. This could be due to a bad ignition coil, spark plug, fuel injector, or valve train issue. If the issue is not resolved, further damage to the engine or catalytic converter will soon follow. I suggest having a qualified technician diagnose your Check Engine Light to fix and avoid more damage to the engine.
