Why does my car keep stalling when its cold?
Cold stalling problems are the most common because the engine needs a richer fuel mixture to maintain idle speed until it warms up. Intermittent cold stalling problems are almost always fuel-related. Or, a defective coolant sensor may be telling the PCM the engine is colder (or warmer) than it really is.
Why does my car stall when the temp is cold?
If this sensor is telling the computer that the coolant temp is at 200 degrees, but it’s actually only at forty degrees, the computer will command the injectors to introduce the wrong amount of fuel for a cold engine. Once the engine gets hot enough again, these problems disappear and the engine runs normally. maffeidj July 5, 2016, 8:40pm #7

What causes a car to stall after too much wear?
After too much wear (IE if you have defects, overheated the car, neglected oil changes, bad combustion over time etc etc etc) the piston rings and cylinders will not mate and seal properly causing low compression and blow-by. While cold, the ring-cylinder mate is tight, keeping the combustion gasses from blowing by and allowing the engine to run.
Why does my car stall in the Cold?
Engine stalling is more likely to occur during cold weather or when starting a cold engine. So, this kind of engine stalling problem often means the engine is not getting enough fuel and/or too much air. A cold engine needs a fairly rich fuel mixture to start, and to idle smoothly while it warms up.
Can a car stall with a bad throttle position sensor?
The engine can stall for no reason and without any warning. This happens when the TPS gives incorrect information to the ECM. The engine can stall at high speed, at low speed, or even at idle. A faulty throttle position sensor will not let your car accelerate normally. Though this doesn’t happen all the time.
