I was on my way to class a little while ago and my cruise control started blinking and my check engine light came on. I pulled over and I checked my gas cap and my oil and made sure everything was on tight and it was...so I took it to the subaru dealership but no one was there to look at it. The lady there said it would be about $108 to get it checked...Is there anything else I can do to see if it goes away??
