I REALLY need help...Please!!! My daughter has a 2008 Mini Cooper and I have spent $2-3,000 (at the minimum) over the past 5 years having the Oxygen Sensor replaced. She made a trip to Nashville to school 2 weeks ago and it happened again. ( the car runs rough, stalls out under 1,000 rpm and the check engine light is continually on ). She called me about 30 miles NW of Nashville and it had happened again. So, long story short, I stayed on the phone with her until she got there, we had a relative recommend a foreign car mechanic, he called me the next afternoon and said, "David, they've been putting the wrong 02 sensor in this car. At last...the problem solved! She drove to Milwaukee Monday and started home today...about 10 miles North of Springfield, IL it happens again!!! I had her drive to an Enterprise Car Rental, get a car and she's on her way home now. Problem is Wednesday I have to drive that rental car back up there and pick up her Mini Cooper. I have no idea what to expect!! I'll try to make it home to Central Missouri. ANY advice you can give me on this issue would greatly be appreciated. I have no clue what to do. Many thanks. doccollins93@att.net. I'll also check back on this post.
