Frustrating CEL problem. The above code pops every coupla weeks on my daughters car. When it pops the fuel trims are out of whack. When its off the fuel trims are good. seems to happen on cold days and goes off on warm days..over 45 degrees. I replaced Mass Air flow sensor, and now am leaning to MAP sensor? Any ideas??

Weather turned cold and CEL popped again..same P0171:00-68...any more ideas..It has to be some kind of a sensor that measures outside ambient temp and sends it to the computer.??
