When I start the car up in the morning the car seems to go though the ECU learning even if I do not dis-connect the battery. The battery reads 13.1V with no draw on it and when car is running the car itself reads 13.7V. No Codes, no lights no power issues, just seems to have to relearn every day. It seems when the car learns and is warm it is fine the day but in the morning when I start it cold it goes thought learning again. Hard bobble, almost shut off, then revs up and idle gets smoother over minutes till fans come on then its done. Next morning same thing. Anyone encountered this, any thoughts?
