A friend's car stalls, SOMETIMES, but it getting a bit more frequently now. It only stalls when I'm coming to a stop. Sometimes, it would stall while AT full stop. The power steering goes out, but the other things (radio, lights) doesn't. No warning (blinking lights) at all before stalling.
The check-engine does come on when in heavy traffic for a while, but goes away as soon as we start moving.
Any ideas? I can't find anything in the service manual (well, not in the bulletins anyways..)
What can we check?
