ok, so i got some scan tool live data capture for you to look at. I attached it as a text document. heres my other thread with my symptoms. http://www.aveoforum.com/forum/f108/rough-idle-16787/
in the text document in the beginning it was idling at about 700-800rpm. about halfway thru when the load percentage drops is when I revved it up to 2300rpm. you might also note the changes in long term fuel trim and manifold vacuum, and the fuel rail pressure. I will once again say that this car drives fine, but idles poorly. it seems to be leaning it way out at idle and the trims go back to normal when driving. the only code is a p0300.
