95 Ford Contour SE V-6

I have a 95 Ford Contour that started hesitating when it is cold and if I don’t rev the engine when taking off, it stalls. It never did this before it got cold.

I don’t know if I am imagining it, but I think the car also now has a slight miss, once in a while, when at higher speeds.

What might I look at first?

Thank you,

David
