Thanks for your reply. I'm having all three of the symptoms you specified although the car didn't stall at idle for over 2 weeks now so I guess it's more the stumbling and the poor reving that are issues.

I think you may be right about the alternator because my a/c started making a terrible sound when in use and someone on focaljet told me it might be caused by a bad belt, a bad alternator or the a/c compressor so it would make sens that the alternator is the cause of both of these problems.
