The 2023 Dodge Challenger represents the final production year of this iconic muscle car, featuring the full range of powerful engine options. When a P0304 code appears indicating a cylinder 4 misfire, understanding your powertrain ensures accurate diagnosis and restoration of full performance.
Understanding P0304 in the 2023 Challenger
Cylinder 4 location varies by engine. In the 3.6L V6, cylinder 4 is on the rear left bank. In all HEMI V8 configurations, cylinder 4 is on the right (passenger) bank. The engine control module monitors each cylinder's contribution through crankshaft position analysis.
Final Year Production
As the last model year of the current Challenger generation, these proven powertrains have reached their most refined state. If your 2023 model is within warranty, component failures should be covered. The HEMI engines remain strong and reliable when properly maintained.
Diagnostic Process
Identify your engine configuration and access cylinder 4 accordingly. Inspect ignition coil and spark plug condition. On 5.7L HEMI models, note whether misfires correlate with MDS operation during highway cruising.
Resolution Strategy
Replace spark plugs with Mopar specifications. Test ignition coil output. Verify warranty coverage for applicable repairs. Address any MDS concerns on 5.7L models.
