I have a 04 cavalier when coming to a complete stop it acts like its going to just stall its a 5 speed also

 

A simple thing that can cause that is a vacuum leak. Check all your vacuum hoses under the hood for a leak.

 

My 03 does the same thing. There is a TSB out that explains what is going on, and the fix for it is to get the ECM reflashed. I haven't had time to get mine done. Does yours sometimes act like it idles down so far and quits, then at other times tries to idle at 1500rpm?
