My 2006 Dodge Charger SE is having issues in cold weather. It seems like the car will not warm up no matter how long I leave it running when the weather is cold. If I let it run for a while and then turn the key off and then back to on it then warms up. Also the heat only runs while the car is in motion. A lightning bolt symbol is also visible on the dash when I start the car until I have to cut it off and back on to get the car to warm up. Again these symptoms only appear in cold weather and not warm weather. Thanks for any help.

take the air temp sensor off. and leave in warm house. till at your homes warm temp then go out and install the sensor.and start engine. if it starts this is your problem.
Check all vacuum lines first for any possible leaks especially if you have a flow control near firewall or hoses going through firewall. If you feel hoses going to heater core, are they both hot to touch when engine at normal running temperature? Coolant level is up, and been bled properly? Did you have to add coolant lately for any reason?
There is a door in your air intake that is thermoststicly controlled that is to remain partially closed until tge engine warms up.Thereby letting in cold air on a cold engine, causing it to run rough.
could be cold oil in the power steering making the pump whine or in the transmission
may be a transmission oil change or pump oil change could point to the problem
well the 1st thing u need to do here is have the electronic engine control system tested for fault codes, this is the very 1st thing we do in the shop for any problem like this, the idle and all other functions are monitored and controlled by a powertrain control computer.
I recommend a trans fluid and filter change first. It definately sounds like the problem is in the trans. If it was any sort of engine component you would have had a check engine light on.
if the weather has changed and got cold your tire pressure would have dropped and would be lower. 2 options. 1 is fill ther tire to 30 psi and ride it out (remembering that when it warms up the tire pressure will automatically go up too)
2. Is to run a dry air such as nitrogen which does not change pressure in hot/cold weather. Hope this helps
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.
cable is fine,can be the tps but try tapping on the idle air valve and see if the idle kicks up,it works like a choke and if its stuck its a big vac leak
