I've had this problem in my 1991 Escort. Try this, replace your spark plug wires and/or check your pcv valve it could be clogged or not even connected to valve cover. if replacing your spark plugs and checking your PCV valve didn't work check for a vacum leak in your intake and exaust system

Why would a 1993 Olds Acheiva stallout and die whenever it's in gear and idle rough but it will stay running in neutral?
Most of the time rough running and stalling is due to vacuum leaks. There is more of a load on the engine when it is in gear, so that lends itself to stalling out. When I look for vacuum leaks, I have the engine idling (maybe you need a friend to keep it from stalling) and then spray carburetor cleaner around the various hoses & gaskets that could be leaking. Any increase in the idle speed would be an indicator that you have a leak in that area.
