As stated above. Cold start, everything is fine in park. Warm-up has normal enrichement up to the closed loop point 100 degrees. If the vehicle is put in gear or neutral, the wideband goes full lean which is believable because the engine runs really rough. ECM does a great job of compensating when in closed loop. I have added fuel, to the bottom end of the table, actually quite a bit, but it hasn't helped. Ideas?
