Heat oil in skillet over medium-high heat. Dredge pork chops in seasoned flour & brown in skillet, turning to brown both sides.
Layer chops in crockpot w/ onion slices. Pour chicken broth over. Cover & cook on low X 7-8 hours (or on high 4-5 hours).
Stir the 2 T. flour into the sour cream until smooth. Remove the chops when done & add the sour cream mix into the cooking juices. Raise the crockpot to high X 15-30 minutes or until the liquid has thickened.
Serve chops over noodles or rice w/ the sauce.

I got this list in the email the other day for Crock Pot dishes; but I have no idea how good any of these recipes are.
