My code reader has live data display. Running through the information, after changing plugs and wires, I noticed the very last item shown was a long term fuel trim reading 'b2s2ltft 99.4'. Is that a normal fuel trim value for that sensor? I will reverify on way to work, in AM. I have a 10 mile drive, one way, and should show up, again. Is a reading that high a sign to worry about?
