2001 Dodge Caravan SE 2.4L.. In cold Weather it starts then stalls and dies...?

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.

    ok you replied to my other post but i dont know which you will check so i will reply here as well....I get what your saying about it controls how much fuel to on the same page with you on that one. Where is the throttle body temp sensor located? how much does it cost?
    Is it hard to change?
    I trust your word that it most likly the problem but when i start the car how can I test it to ee if the throttle body temp sensor is the problem before I buy one or is it hit and miss I just have to buy the part and see if it works?

    Can it be scanned and tested by a regular mechanic as well instead of a chrystler dealership? Because I have some mechanic friends who could check it out for me and not presure me into paying right away...

    Ok about the heat....I didnt feel the heater core hoses with the heat cranked yet, but tonight when i was driving the van it was about 47 degrees outside. It actually started up and drove fine, when I put the heat on low and regular it came out hot for 2 minutes then turned cold. When I turn the heat on medium and hit the circulate button (you know the one with the pic of the van and an arrow sweeping throw it) the heat came out fine nice and warm and it worked okay. Does anyone know what this means? it is a clogged core or does it mean there is a vacuum leak somewhere. For example it only forces a certain door open on a higher setting? Any advice and opinions are greatly appreciated...I would like to get this heater going before it gets any colder and the snow gets here....thanks

    okay i felt the heater core hoses while the heat was on high and they were both piping hot...the heat works on a low setting with the circulation button pushed on but when the button is off the heat comes out cold....could this be a vacuum leak? anyone?

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.

    Easiest way to tell for sure is to have it scanned at a Chysler dealer. Maybe a call for quote on just a scan would be a wise thing. I always figure I'd rather have it scanned for $30-$40 and save $ 500 in parts from guessing. Working for a Chrysler dealer, I seen many a guy by a part (non-returnable electrical part) , one after the other, because a friend had same problem and this fixed his, or neighbor or whoever, only to see them spend up to a $1000 in the end, on non-returnable parts,to find out it was just a bad connection at Engine Control Module.

    Yes , a good compotent mechanic could do it, provided he has all the proper software on his scan tool. He may even come up with other codes while at it, but he should be able to clear all codes and start over, which would allow you to drive it a little, and make sure what codes re-appear, just in case some were stored and not erased prior. I would be looking for a code relating to air inlet temperature or similar, and if more than one code, fix that one first, erase codes, then run it again before replacing any other part. Sometimes one part malfunctioning can cause 2 or 3 codes to pop up & once the initial problem is fixed, they go away too.

I have a 1996 dodge caravan that starts hard in cold weather!

Cold weather has an adverse affect on batteries. The clicking sound could be from the starter solenoid not receiving enough voltage to energize the starter motor. The engine being hesitant to start and run could indicate the need of new spark plugs, wires, etc.

Sounds like you have a broken fuel return line. The high pressure line goes through the filter and to the injection system, and the unused fuel is returned through the pressure regulator back to the fuel tank.

Your coolant sensor may be stuck in advanced timing mode. Change it & the engine will start easy in cold & warm weather. The sensor is located near the thermostat housing.

Van won't start in early morning when it's cold.

I'd be real tempted to replace coolant temperature sensor, as it sends signal to ECM regarding engine temperature and fuel requirements pertaining to that temperature. For example, it tells ECM that engine is cold, send more fuel for cold start, but if it's defective, doesn't tell ECM to do so, or gives ECM the signal that engine is already warm, and doesn't require that extra fuel now for start up.
