My car was running great yesterday but this morning I went out to start her and she started idling very irregular then she stalled. This irregular idle is like a rapid surge in idle speed up and down rapidly over and over. She will not stay running. If you gas her she is fine until allowed to go to idle and then she will stall. The only mods to the car is a mac-chamber (mil-elims also) and a cai. The air-cleaner looks fine. I've had some evap-emission codes thrown for some time but nothing serious.

If anyone has any suggestions of what could be wrong and how to troubleshoot those issues please post. Thanks
