Just about done with my kit. 2023 with 2.2 5 speed. Is there any way to adjust the emergency brake cable. You can feel it grab a little but not nearly enough. Also, have an annoying rattle when shifting up. Checked the rocker arms and the lash adjusters and they seem fine. Third, the idle speed is around 1000. Any way to adjust it down? Thanks .

Did you clean or play with the butterfly on the throttle body at all? I cleaned my throttle body once way back when I had 210k on it trying to be nice, the cobalt didn't like that, the cobalt computer can relearn the idle but it might take it a while. when you get to a stop let out the clutch a little with the brakes on until the rpms drop to where you want them, hold that for a second or two and then you can push the clutch back in and it should hold the lower rpms but the next time you stop you will have to do it again. Mine took a few months to learn the lower RPMs. this was in the Cobalt when I did this and I was daily driving it so in a vehicle you drive every now and then might take longer. Others may have a different way to do it but this worked for me.

I think there is a threaded adjustment on the cable at the handle.

A vacuum leak can cause a high idle. If nothing else is wrong, HP Tuners can adjust the idle on most of the Cobalt donors. The early base Cobalt can't be tuned with HPT.

The slack could be taken out at the threaded rod under the plastic handle cover.
Also, don’t pay attention to how far out mine is adjusted. I don’t have any cables at the moment.

Stock clutch or aftermarket clutch? The clutch can be a source of a rattling noise when stopped and in neutral or with the clutch pushed in - if coming from the driver's side of the engine bay.

I had to do an idle relearn on the wife’s Goblin which is 2007 2.2 5spd. I cleaned the throttle body and It would idle at almost 2500. My tech2 didn’t have the idle relearn in special functions but the idle air compensation was 100%. I entered it in the tech2 as a 2008 and I think 2.4 engine and had the idle learn then I was able to reset it
