car stalling when engine is cold
 

My s40 2000 stalls when the engine is still cold, it needs about 4 minutes of iddling before it can take off, any suggestions please to fix this problem, thanks in advance

OJ, its best to post your questions specific to your car and year directly on the S40 board. Possible causes include dirty or failed idle air control valve, engine coolant temp sensor, air intake temp sensor/preheat flap actuator, vacuum leak. Do you have a check engine light on? If so, have the OBD2 codes read for clues. I'd start with the easy - check your vacuum lines, then consider cleaning the idle air valve, then measure the coolant temp sensor's resistance (look for something on the order of 2000+ ohms for cold, 300 or less ohms when warm)
