Hello,
I have an 07 MINI COOPER hatchback. Recently my car has been shaking really bad when I drive it like I normally do. It scares me because at a constant speed it slows down and shakes on its own. At stop signs or when I just turn it on, it shakes and it sounds like it gets quieter and just DIES!! I then have to put it back in Parking and turn it on. Also its throwing a code of CCID 031. My check engine light has been on for 2months now. The closest MINI dealer is 2hrs away. We just changed the alternator belt because it wasn't charging the battery. Also, my car jerks really hard when it gets speed at first and changes gears. My sister accidentally put regular gas when it takes premium but my dad put a gas treatment, he's a diesel mechanic but he says gas and diesel motors arent the same. PLEASE HELP!!!
