Thanks for the responses! After my post last night, I also googled the two error codes and "Cobalt." I hit on a post on a Cobalt SS forum where they had a similar problem. They never confirmed the fix, but speculated it was the ECM. However, they also said they could clear the codes and the car would run again for a while. So I tried that and, to my surprise, it ran. Not great, but it ran. That made it possible for me to jiggle wires, per your recommendations, and I found an area where, when I touched the engine wire harness, the engine would die. I dug around there and found that, as you suggested, one of the engine ground wires was loose. So I got it reconnected and now it runs without dying when I move the wire harness.
However, it is still running rough. Now I'm getting the following errors:
P0204 Cylinder 4 Injector "A" Circuit
P0300 Random/Multiple Cylinder Misfire Detected
P0304 Cylinder 4 Misfire Detected
So, tomorrow I'll continue to troubleshoot the Cylinder 4 issue. If you have any additional suggestions, please let me know. Thanks for all of your help,
