问：引擎停下来时死亡。

上周五，汽车在道路尽头的停车标志上死亡。我能够将其恢复原状。第二天，对电池和交流发电机进行了测试。电池不好。我更换了它。由于防冻剂遍布发动机，因此更换了散热器周日。周一开车15分钟。它死于停车标志。不会重新开始。试图启动它，它开始通过通风口吹烟。 Got off work Monday night and was able to start it back up and drive it home. Died when I stopped in the driveway. Someone plugged in a thing to check the engine light. It popped up a code that said co2 sensor was failing. He said that would only affect gas mileage. Had my oil changed Wednesday. Tried to drive it to work again. It died at the same stop sign 15 minutes away. Just got off work. Was able to start it up and drive it home again before it died when I stopped in the driveway. There is fluid in the radiator. Hoses are good. Don't think it's leaking anything.
