Why does my 2008 kia spectra idle rough with the AC on ?

What is your question?

I just bought my 2008 kia spectra 184,000 miles .. Sometimes if the AC is on it idles really rough and feels like it's trying to die never does but once it warms up It's fine . Still has low idle with AC on at a stop light

What makes this problem better or worse?

Worse with AC on

How long has your 2008 Kia Spectra had this problem?
