I'm not sure disconnecting will be enough. Car could run with last stored fuel trims (instead of zeros). And those may be seriously bad. IMHO better is to delete adaptations and see if car runs any better. It will not begin adapting until sensors warmed up anyway, so you will have a minute or two before that.
