I just reviewed and cleared all codes using my OBDII scanner device. There were basically 3 different codes that were repeated a few times each. I changed the front O2 sensor so am not worried about those anymore. There were a couple of instances of turbo overboost, which I assumed to mean a vacuum leak. As indicated by me previously, we had a problem in that the air intake hose was loose, thus causing the car to die and the brakes to function poorly. I am going to assume for now that this was my "vacuum leak." The other gave me the impression that it is an issue with the mass airflow sensor. However, after reading posts on other sites for a similar stalling issue, I am inclined to believe that it is an idle control sensor.

At any rate, I have erased all codes so I can start with a baseline and will work forward from here. Cross fingers, but I think the only remaining issue may be the idle control sensor. If I continue to get the aforementioned code, that is the part that will be on my hit list.

I will provide updates as they occur. Thanks for your help!
