Throttle Position Sensor, Choke, E.G.R., MAF sensor, one or another among a few, could have gone bad. Oh and Yes, a vacuum line has come undone or has eroded. One or a hundred things could be causing this problem. Y-THINK-Y
The thermostat control engine temperature. If it fails the engine can run hot or cold - that would happen long before over-heating caused the engine to stall.
No, it would not. There are many things that could cause a stall at idle. The throttle plate could be dirty as well as the mass air flow sensor. You did not mention the kind of car or engine size. Is the check engine light on, is it when the engine is warmed up or cold?
Stalling at idle? Immediately after starting? While driving? While stopping? Cold or hot engine? What engine do you have?
bad fuel filter
could be that the choke is not adjusted right
This is a electronic fuel enjected engine and therefore the electonics set the engine idle speed a bit higher during a cold start so the engine will not stall out.
cold engine
I would check the ignition system. Warmed engine stalls can be caused by a failing ignition coil or coil pack. Pull a plug wire, crank over the engine, and evaluate the color of the spark with engine cold and engine hot. Snappy blue at cold and weak yellow (or none) at hot and it's time for a fresh coil.
If the engine runs cold you might try replacing the thermostat. I had a similar problem with a Plymouth van, at low rpms, turning corners,,, it would stall.
Usually, a jeep's engine stalls in idle mode because of a battery power fault or because there is no gas. However, it is common for any car to stall when it has not been running for a period of time and the engine is cold.
It means the engine stopped running.
A cold wind should have no effect on the car engine.
