Default Inconsistent idle

Hi guys,

I'm new to the forum with a 9-2 2.5i. It has an automatic transmission and 92k on it. The car idles inconsistently. When the engine is warmed up, and I am stopped at a stoplight or something, the car fluctuates between normal idle speed just over 800rpm and then drops to around 400rpm and you can feel it struggling... This occurs both in drive and in park and fluctuates about every 20 seconds or so... Once on the go the car doesn't seem to be affected and drives normally. The check engine light has also recently come on along with a flashing cruise light...

Any ideas? Thanks!
