There is a temp sensor that is designed to tell the computer both ambient temps and coolant temps. From that, the computer determines how rich or lean to make the fuel mixture for cold starts.

Just to add to this one I would go for the coolant temp sensor its so common on that car for them to go bad and cause all kinds of symptoms.I would also inspect the connector to it really common for them to get corroded from the coolant temp sensor leaking coolant into them. If the terminals are green or blue instead of silver inside the coolant temp sensor connector replace the connector also.

The sensor is screwed into the head right bellow where the upper radiator hose goes on. It has two wires going to it a black wire and a yellow wire.

Saturntech9: I was hoping you would jump in on this one. Do you feel confident it is the sensor? That is what I was thinking.

Yes I think its the coolant temp sensor and possibly the coolant temp sensor connector.
