    I am having the same problem with my '02 Deville...the car runs great while driving but when idiling the RPM's frequently goes back & forth from approx. 650 to approx 400. The RPM's dropped so low a few days ago that a notice came on that the battery was not charging...but that just lasted a few moments & then the RPM's went back up to normal. My service engine light has also come on.

If it says system not charging, the alternator is not working correctly. It starts with the battery but, when running, the alternator recharges the battery from cranking as well as keeps everything else working. Since the alternator isn't putting out enough power, it shows a fault.

Changed battery, replaced with new battery, car won't start


Somewhat vague question, you don't say if it's cranking or not. If it isn't cranking then have your starter motor checked, if it is cranking check for presence of fuel and spark, report back please when you've checked.
