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.

Have you had the codes pulled form the ECM to see why the light is coming on? It may not store a hard code, but there may be something in "freeze frame/failure records" that will help out. It sounds like the Idle Air Control valve may be going out, but it would be nice to see what the ECM says
