It sounds to me, especially if your cross track error is jumping all over the place, that you have an issue with your antenna.
That said, the autosense is notorious for causing problems, as is the short gray cable that connects to the autosense. But, I'm leaning towards an antenna problem more than anything. Do you have another one you can swap out? Even if you just have a WAAS antenna laying around, that should tell you pretty quick if it's the issue.
