The numbers going into the negative range is perfectly normal. The LTFT are the rolling average fuel trims. Ford's technical boards state that if the remain in the -+ 7% then they are ok. The STFT are the instant feed back from the O2's. It is typicall to see thes go +17 or so during acceleration and - during decel.
