Our expedition when we start it up in the moring sometimes sounds like its gonna shut off, but doen't, and there are also times when driving home it seems to do the same thing. It doesn't happen all the time, but is growing concern. My thoughts were perhaps it needs a new 02 sensor, but thats a guess
