I recently purchased my 99 mustang gt from a auction and the check engine light is on. My car hesitates a bit when drivin almost like a miss. I checked if it wasn't firein on all cylinders by unhooking each coil pack and the car ran worse so i knew it was firin on all cylinders. I was wondering what could be wrong with my car and how do i check the engine codes my self?
