I live in Ft lauderdale and i was caught in high water. I made it home fine. The next day when Indrove the car the check engine light came on. The acceleration kinda hesitated a little right before the check engine light came on. Now i’m getting codes P0303 and P1315 anyone know what this might be? It says cyclinder 3 misfire

 

Usually caused by a bad injector ( I had mine changed years ago ), bad spark plugs, or bad coil. I would clear the code and take the car for a long drive to get it hot and see if the fault comes on again.

Since the car was in high water I would bet on the coil
