Danikwood75 did you ever get your problem resolved? I have a 2007 Lincoln MKX and it is having the same problem, except that it is when I turn right. Loss of power and a sudden jerk. The OBDII scanner that I use says that I have a B1278 error, Steering wheel angle sensor 1 & 2. I have it at a dealer right now to get it looked at and I think that it is the steering angle sensor, but I am just wondering what you did to get yours fixed.
Thanks
Chris
