nissan

#1

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

This all happened after driving through heavy rain


#2

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!).


#3

Replace the coil-on-plug boots.
