Ok, so I got frustrated, took it to the mechanic down the street. He diagnosed the stalling/rough idle as an EGR problem. I repalced the EGR myself. On the test drive, I barely made it back home. It was doing the same thing. I since have been driving it once in a while locally, and it seems to be ok now. The mechanics secretary told me I need to give it a few days for the computer to "adjust" to the new part. I thought that sounded odd.
I noticed in a post from CWL(?) that he prelaced the EGR, MAP sensor and another sensor. I was curious as to how the vehicle is now running for him(since the post was in '06).
