My wife's 2000 Taurus has recently developed a strange problem. It doesn't happen often, but twice now in three days, when she turns the steering wheel sharply the car dies. Both times, the car has been at a near idle, but under no extreme load. She had a check engine light on for the DPFE sensor, but when it died the first time, the light went out, and hasn't returned, yet. I'm having a hard time figuring out where to start. My first thoughts are a vacuum leak because of a braking oddity and the DPFE sensor. Maybe some strange electrical issue, or fuel. Any recomendations? Thank you for the help!
