2011 Aveo kicking multiple codes

[Deano]

In my opinion, a bunch of codes that happen around the same time suggests a wiring or grounding issue. Have you checked the wiring harness to chassis ground connection right beside the underhood ECM? I would wager the mounting surfaces at that ground connection are rusty. Check that first before troubleshooting any further.

I haven't checked that but a lot of what i read pointed to the ecm being bad. I will check that ground. other than that do you have any other thoughts?
