I would be calling to ask about why it won't load saved tunes.

is it same o2 sensor as before, or new one with the repaired kit?

I don't know about that setup, mine periodically asks for recalibration.
if it was the old one with fuel dumping into the system, it might be over saturated and you need to pull it out into fresh air and let it heat up and have it recheck 0.
