2004 Nissan 350Z - Heavy rain now misfires

Misfires on multiple cylinders
Car stalls below 800rpm ( idle)

This all happened after driving through heavy rain

While it’s dark out, open the hood and start the engine. Look for sparks near the ignition coils. Dry off those areas (WITH THE ENGINE OFF!).

Replace the coil-on-plug boots.
