P0303 on Honda vehicles
78 owner complaints filed with NHTSA about Honda vehicles mention P0303 (Cylinder 3 Misfire Detected) - across 9 models. Below is where it shows up, by model and year.
Can you drive with it? Short careful trips only, and only while the check engine light is steady. A FLASHING light means stop - raw fuel is overheating the catalytic converter, and a glowing converter is a fire risk.
Symptoms, likely causes in order and realistic repair costs are on the main P0303 page - they do not differ much by brand. This page shows what is specific to Honda: which models and years actually report it.
