Practical tips for DIY work
When performing spark plug replacement, coil removal, or diagnostic work, label or photograph each coil connector’s position to preserve the correct firing sequence. Use the cylinder numbering convention described above to arrange wires or coil packs correctly. If you suspect a misfire, run a live data check for misfire codes (P0301–P0306) and test ignition coils and plugs accordingly.
