3 Codes For The Newb

[Big-E]

Heres my problem http://kia-forums.com/t9217-help-stalling-problem.htm

I went to the Autozone and had the codes pulled P0140 P0101 P0172. The CEL would only stay on after startup and would go away within 5 minutes. The CEL came on one rainy day after my wife almost rolled it. Then ever since the CEL would come on after firing her up(the car, not my wife) then turn off after 5 minutes so I never thought about it. I had the guy clear the codes and the CEL has not come back on in the 3 stops I have made since stopping there and getting them cleared. Do they have any relation to the problems Im having? What are the codes and how can I get them fixed or should I not worry about it till the problems and codes arise again?

Hey,...its me again. They are related to the heated oxygen sensor circuit being faulty. A bad signal can lead to a bad fuel mixture. I would focus on this circuit. I have heard it could be a specific fuse for this sensor.

As said before, if the ecu is getting a bad signal it will mess with your fuel mixture causing cascading problems.
