The EGR valve is fully closed when cold and opens when the engine warms up to normal operating temprature. Check the EGR valve to see if its closed when the engine is cold. If opened replace it

Do you get a check engine light? Generally this problem can be caused by a leaking injector or the "cold" enrichment (modern version of a choke).

I recommend you to go to your local Autozone store and ask them to check
your vehicle for emissions and other engine problems.
This is a free service. They will show you a print out of the probable causes of the problem you are having and the cost of the parts you need to fix your vehicle.

Caravan runs very rough at start up when cold


have you installed new plugs lately,if so have someone check the Engine Coolant Switch,

1 Answer

Only runs rough after running and fully warmed up


when it is cold there is extra fuel going to the plenum chamber its like pulling a choke on a carby that is why it is running smooth but when engine gets hot it is back to normal supply of fuel and yours is not normal.one reason might be not enough pressure in the fuel rail due to defective fuel pump or pressure regulator or blocked fuel filter. it is best to check your fuel pressure first.
