P0303 Fault Code - Diagnosis and Solutions for 2019 Kia Niro

Hello everyone, My check engine light has come on, and after scanning with a code reader at Auto Zone, I received the P0303 diagnostic trouble code. This indicates a misfire in cylinder 3, which is commonly associated with ignition system issues. The technician suggested replacing the ignition coil as the most likely cause. However, I'm wondering if there are other potential sources of this misfire that might not involve the coil. For example, could problems with spark plugs, fuel injectors, compression, or engine timing be contributing factors? I'd appreciate any insights from owners of 2019 Kia Niro models who have experienced a similar issue or know how to troubleshoot P0303 beyond just replacing the ignition coil.
