Engine stalls while driving?

Thank you for the guides and advice. I had this problem and got a new sensor from Amazon to fix it. :)

I have a 2005 Chevy Cavalier that sometimes stalls when driiving at 55 to 60 mph also sometimes it will start and stall, you keep cranking it, it won't start, but if you turn key off and try again it will start and die again, if you pump the gas before dies it wiill run. May run fine for day or two then problem happens again. I changed fuel filter, cleaned IAC valve. I took it to a GM dealer, no codes where found, they suggested replacing instrument cluster and going from there. Do you have any ideas, could it be the BCM module?

Thanks,

I have a 2004 Chevy Cavalier 2.2 manual trans. Car started shutting off when coming to a stop and when slowing down for sharp corners. Usually starts right back up, sometimes not. When it doesn't start right back up, wait about 5-10 minutes then it will start. Idles extremely rough. Check engine light on from time to time since it started shutting off. Car has been to 3 garages, including a dealership. Checked by 4 different computers. Changed plugs, coil pack, ignition control module, map sensor, throttle position sensor, upstream O2 sensor, ECM changed, Air box changed. Had fuel pressure test done, and also had the catalytic converter checked. The more its driven, the more it shuts off. Suggestions? Is the crank sensor a possibility?

Only code being thrown is System Running Too Rich. Even after all the things mentioned have been changed.

P0172. That upstream O2 sensor has already been changed.

Already did the pressure test

No

The cars rpms run so low that when I stop at say a red light then take off again it doesn't want to accelerate. To get it to go even 30mph I have to get it up to 4000 rpm. But it is only sometimes. Once the car get up to about 40mph everything works fine though. The car has even died a couple times at a red light. And when i'm parked and the car is idling it fluctuates around 5000 and 8000 rpms, like it is surging.

Thanks, do you think it could be the fuel pump going out?

My 04 cavalier didnt want to start so I charged the battery and it started but now 3 days later it starts and shuts off within seconds. Check engine lights been on for about a year reading an evap emmisions leak

I would definitely have your codes read. While it may be on for the evap problem that you are aware of there also could be other codes showing and you just dont know it. It is always best to fix the problem and delete the codes.
