I have a 2005 Cobalt with the 2.2. I am currently having a lot of issues with it. It has a very rough idle. Sometimes when I come to a stop it shuts off. It starts right back up though. Usually when I am at a red light I have to put it in neutral so it does not shut off. Here is a list of things I have already had done to it...

Tune up
Oil change
MAP sensor
Throttle Body Cleaned

Anyone have any suggestions on what to do next or has anyone else had this issue?

Do you have any engine codes? Does it misfire?

There is no misfire. It does have the o2 code showing but a lot of people said they've changed that and it hasn't fixed the issue. Just trying to save some money if I can. It's basically just a beater with a heater so I don't want to put too much into it.
