My check engine light is flashing and stabilitrak keeps popping up. What should I do?

I would not count on that. What you need to do is have the car scanned and write the codes down. So check you favorite parts store and see if they do a free scan, have them scan it and get the codes then have them clear them. Get back to me with the codes and I will look them up and tell what we should do next ok. Be prepared you may have to have a shop scan it as most low priced scanners don't read ABS or Trac control codes ok.
