So I went to the carwash, about 2 miles after leaving the wash my "Service Engine Soon" light came on... I went into the troubleshooting mode on the Accessport and there was 2 codes, one was the MAF sensor was faulty and or needed to be cleaned, the other just says ECU and when clicked on says " No Description Available" . The car runs and drives the same as it did before. What could cause the ECU "code" since it does not specify what code it is? Could it possibly be water got into someplace it shouldn't have? Any help would be greatly appreciated!

I'm no expert but your initial assessment is probably right. Your AEM intake still has the box around it right? Seems unlikely to me that any water could get through, but if the car's fine and the CEL is gone it's probably a bit of water that got into the system.
