I lessend the time to where our truck will go into closed loop. It pulled up a
o2 heater code the next day. I'm guessing that's because the O2 was not realy ready to be in closed loop yet. (sound right?)

I'll have to get the open loop fuel richer.. it's awful lean when its' cold and I know it's not in closed loop...> I'll just try and put a few more numbers in the lower sections of the open loop fuel tables.

Sound like I'm on the right track?
