I'm the one with the car (van) that wants to stall after starting. It is a 2001 Ford Windstar (a grocery-getter), so I am guessing it is not old enough to have the carbeurator issues. And it doesn't seem to depend on the temperature outside or in the engine, as it tends to be a little slow each time it is started, but then it seems fine once it has been driven even just a couple of miles.
This morning, it even hesitated (VERY slightly, just barely enough to notice the difference) to start, but once it was running and I drove about 3 miles, it idled fine. I got to school, left the engine running, put it in park and got the kids out of the vehicle to go to summer school and it never coughed or hesitated or threatened to stall. So it only happens when I first start it.
We're in the market for a new vehicle, but I'd rather wait and get one I WANT instead of being forced into it because my current one died! So if I can keep it running for a few more months it would be great.
Dont want to hijack, but you should also check your battery and fuel injectors. There is a couple other things but I cant think of them right now, I will come back when they come to me.
