SES light on with engine sputter
 

Hello peeps,
So after driving in the rain my engine started to sputter and today the SES light came on. I tried having autozone read the code but they couldnt read it. I checked my gas cap and it was a little loose but i tightened it and went for a drive. My engine was still sputtering. My mods are Berk HFC, ingen catback exhaust, and AEM CAI with Uprev tune. It could just be water where the spark plugs are but i cant pull them out untill saturday. Any response would be very helpful before i start troubleshooting on saturday. Thank you all. I have read through mutiple threads but i havent seen anything close enough to call it. :bowdown:
