So its has been a week and still going great.One cel/code popped up which was a p0171(bank 1 system lean.)This only happened once on a 95degree day with high humidity the AC on stuck in traffic,cel turned off on it's own the next day so i am sure its because of the conditions that day caused the cel.High humidity not good.

Did you do a coolant line bypass on the 1ZZ TB? I did, and I've literally never had a CEL with my TB.
Although it may not be advisable under very cold weather for what I hear (we don't get too many of those down here)...

Kou, i also have the same symptom as yours. AC on, stuck in traffic, CEL on. But my error is p0172(bank 1 rich). CEL went off on its own on the next day.

Now still monitoring what causes this CEL.
