I hope you can help me. I have had 3 mechanics look at my Volvo 850 and no one can discover the problem. I start the car from cold. If I don't warm it up for 10 minutes, and stop at a light within a mile from driving it, the car putters and then stalls. This usually happens on cold new england days and now has made the car very unreliable. When it stalls at the stop light, I can't start the car up again for 30 minutes. I turn the ignition, the light comes on, the engine tries to turn, but nothing starts.

Any ideas? We've check all sensors, feul injection, etc.

Thanks!
