i have a 2004 mazda 3s it seems like when the weather is warmer with my ac on the idle becomes rough. It will bounces between 750 down to 500 or ready to stall. the ac turns off wont work for a minute or so then comes back on. it seems like its cycling very often. I can be stopped or at various speeds and the idle drops ac goes off then back on. hope someone can help as a live in Florida and need ac running properly. Thanks for any help
