I think your MAF sensor got wet especially if it was raining hard like you said in the email, clear the codes and look at both MAF voltages to see if they are even voltage wise. you Should see around.8 to .9 volt at idle . Rev the engine and see if the voltage is increasing smoothly. If all that is good then i think you got lucky and the sensor did not get damaged.

If the sensor got wet then there is a possibility that you might have still some water left in the intercooler, You should check and clean as needed .

Hope this help .
