Recently moved to Dallas from West LA and need an "M" specialist to diagnose what this emissions light is for. Ran the code says P0303 cylinder 3 misfire.

car idles well- Coil pack is brand new as i broke the old one when i replaced all 10 spark plugs 8k miles ago. removed the spark plugs and they look good to me. Can it be my cats? or oxygen sensors?

and also any recommendations of someone here local to Addison TX.
