I own a '95 Aerostar and I currently am having problems with hesitation and stalling. When I'm driving, it feels as though it's going to stall, especially when going over bumps in the road--not a good feeling! It stalled when I was at a red light and when I put it in reverse. The check engine light occasionally goes on but turns off when idle is even. Also, when I went to check for a code, we couldn't find where to hook up the device.
