I have an 07 mini which is acting strange. I don't know what's wrong w/ it/ It will stall out, for example, today I closed the sunroof and it stalled when I stopped at a light. the sunroof only works part of the time and this time it operated fine but the car stalled. When it stalls the battery has to be jumped and sometimes when I take the cables off it stalls and has to be jump started again. The codes are crazy. They said I needed a timing chain, put one in and did not solve the problem.There are many codes showing up. Another example is when the a/c is on the car will not go. step on the gas and it dies out. When it's running it has no power. can not figure it out. can anyone help me out.
