It's been over two weeks since I last posted that I've had no return of the ce light (P0171). I can report that it still has not returned. I'm absolutely baffled. YMR that I cleard the code twice myself, and that since then all has been well. Also the car ran the same and still does, with or without the ce light; just fine.

ps I guess I'd rather be lucky than good.
