DPFE (Differential Pressure Feedback ) sensor system brakes often. Once you think is fixed, it brakes again. 2 years ago my car started idlelling and stalling on stop signs.I had it serviced and they changed the DPFE sensor (about $300). By the way, the diagnose was not easy, it took them about half a day to find the problem. Tow weeks later, the car started having the same problem and I took it back. The said that the part might have been defective, so they replace it again ($84 more for labor). At that time, my car only had aout 75K miles. 2 years later, same case. I took it back, but now they were not sure what the problem was, so they said ohhh is the EGR valve, that was changed ($140), but the problem was still there.

Then, I decided to change the DPFE sensor again, it was fixed but only for 2 weeks.But now I don't know whether the sensor is defective or the problem is something else. The system is compose of several things and to diagnose the exact problem costs more than the repair and the car is not even worth $1000. For what I have read in other websites, this problem is very common in this type of car. Another thing, the suspension system is horrible!!! To fix this problem is about $900!!! I bought the car when it was 50K miles, I was expecting no major problems, but i did not know that the struts would rust and brake so easily. THIS IS A NO BUY!!! you will end up with no car after 70K miles.
