Question about 1990 Dodge Caravan
I have a 2001 Dodge Caravan SE 2.4L.
In warm weather it is fine, but in cold weather like 30-40 degree mornings it takes a second to kick over and then when it does it stalls unless I give it gas.
I did some research and asked around and I seem to be getting the same answer. Everyone is saying it is most likely the throttle position sensor. It is obviously something to do with the idle because when it kicks over it doesnt idle high it idles low.
Could the throttle position sensor be the problem?
Also the throttle cable should it be tight or have slack in it because mine has more then enough slack.
Please help if you can thanks.
I would not replace TPS or IAC. If it works properly during warm weather, then it should do the same in cold. I would be looking at a throttle body temperature sensor/air inlet temperature sensor. These sensors tell the fuel system how much fuel to send, according to air temperature. Your vehicle needs more fuel in cold weather to start & run properly. If the sensor is telling the fuel injection system that its still warm out, it will only send enough fuel for a warm start & run. As far as heater goes, be sure coolant is topped up and all air bled out, turn heater on and feel both hoses going to your heater core, they should be close to same temperature.If one is a lot warmer than the other, you have a flow problem or blockage somewhere, whether its a valve not opening, or plugged core. Let us know on feel of hoses, and we'll go from there.

Inlet air temperature sensor, also known as throttle body temperature sensor, will do that. Don't go changing TPS, or IAC, as suggested in other post. If they work good in warm weather, they should do the same in cold. Air inlet sensor tells system how much fuel to deliver according to temperature, as engine needs more fuel the colder it is when starting.
