2006 cobalt ss rough idle at startup
As the title says getting a rough idle that slowly works its way out after car is cranked for about 5-6 seconds. Noticeably worse when the AC is on, but still a minor vibration when AC is turned off at start up as well...any tips or ideas where to begin diagnosing this issue would be much help and appreciated thank you.

Here's what I would do first.
1. Clean your Throttle body
2. Check your air filter
3. SeaFoam your car
4. Check spark plugs to include the gap
5. Check to make sure your alternator is putting out the right amount
6. Check your battery
Do you have any mods?

lol, alot of us have it, as far as i have been told, its a vaccum issue... Your car cant compensate for the extra airflow when running your ac (as well as the extra engine load), so far as i know it doesn't effect performance, and yes it is a tune issue
