Help! My check engine light has been on since last night. I was able to use the remote start leaving a restaurant last night, but when I got in the car the check engine light was on. I stopped at the grocery on the way home and the remote start wouldn't work. Check engine light has been on ever since and I am unable to use the remote start at all. The side lights flash like they normally do when I try the remote start, but the horn just honks once now and that's it. I have a 2013 ecoboost model. Any thoughts?
