Millie jerky while stitch regulator is on.

What am I doing wrong? My Millie is really jerky, not being a jerk, but jerky, while custom quilting! I've cleaned the rails and wheels and nothing seems to help. Anybody out there have a solution??

What year is your Millie?  Is it possible that your power cord is getting hung up in the back?  Did this just start?  Are your channel locks completely off?

I am no expert.  Hopefully others will have other suggestions.
