1989 Ford Aerostar stalls at start up cold, or stalls somet

My van will start up, but then stall. But if I see it starting to stall, I keep my foot on gas and it will keep going. Once van warms up, it stays on. But engine light will come on and also go off randomly. I can feel engine idle change when engine light comes on.

Also, when at a stop, mostly when vehicle temp is still reading cold. When I push the gas, the the engine wants to stall or it will stall. Sometimes I can restart it right away, or sometimes it takes a few tries.

Once van is warmed up, these symptoms general go away, but engine light still comes on on occasion.

Please help. I have changed the Ignition Control Module and Coolant Temperature sender.
