The check engine light came on last Thursday in my '13 WRX but when I hook my AP up it says there are no codes. I know something is up though because it has been stuttering when I accelerate since it came on, this tends to happen for the first 5 minutes of a drive. Usually only happens in 2nd and 3rd lower in the rpm's, but sometimes it happens in 5th as well.
Light has gone off and come back on a couple times too. Usually only goes off when I leave work to go get lunch and then its back on when I leave work to go home.
Car is stock other than Cobb stage 1 ots map. 2013 WRX with 30k miles on it. Would take it to the dealer but I'm not sure they are mod friendly.
Wondering if anyone has any ideas on this. I know a code would be helpful but like I said, AP isn't showing one and I haven't had a chance to get anywhere else to scan it.
