Sounds like they didn't do it right. That should fix your problem if you swapped engines like I did.

I did everything you did, I just paid a dealer 58 bucks and it didntwork, I do not want to bring it back if I got to pay for them not to fix it, does anyone know the correct way to do thi procedure, mind you mine is a manual transmission. Brought it back as soon as the light came on after he told me they did the relearn procedure he said I'm getting a p0300 code, so I know it must have not worked. Any thoughts? I don't know if I'm damaging anything driving it how it is? The car runs great has stock 05 electronics.

All I can say is I bet they didn't do it right. I had a local shop try to do it and they couldn't get it to work right. The dealer was the one who had to do it. Apparently you need a OBDII tool that sends a command to the ECU in the car. I'd take it back and have them do it again and make sure the light doesn't come back on. You shouldn't have to pay anything since thats what you took it there last time to fix and they didn't fix it.

My Aveo is still running great, idle is and was fine even when I had the misfire problem.
