The 2022 Genesis G70 delivers luxury sport sedan performance with choice of powerful turbocharged engines. When your G70 displays a P0304 code indicating a cylinder 4 misfire, understanding your engine configuration helps target accurate diagnosis.
Understanding P0304 in the G70
The 2022 G70 offers the 2.0L turbocharged four-cylinder or 3.3L twin-turbocharged V6. For the four-cylinder, cylinder 4 is at the rear of the engine. For the V6, cylinder 4 is on the rear of the left bank. Both use individual coil-on-plug ignition.
Turbo Engine Considerations
Both G70 engines are turbocharged, creating higher combustion pressures than naturally aspirated designs. This accelerates spark plug wear and demands quality ignition components. Direct injection can contribute to carbon buildup on intake valves.
Diagnostic Approach
Identify your engine and access cylinder 4 accordingly. Inspect spark plug condition. Check for boost leaks in the charge piping. Verify no vacuum leaks exist.
Resolution Process
Replace spark plugs with Genesis/Hyundai specifications. Test ignition coil output. Address any boost system issues.
