Hello all I have a 06 cobalt LS that at idle the rpm jumps between about 1k and 2.5k rpm sometimes it dies too. I have tried to tackle the problem 2 times now with nothing working. So far I have replaced all spark plugs, used and engine flush, replaced belts, and an injection flush 2 times. I am out of ideas can anyone help.

Any codes showing? Changed the air filter?
Just cleaned the K&N filter. It shows a air fuel code that I cant seem to find anyone that knows what it is. The only answer I get from Chevy or any other shop that it is a ghost code that means nothing. I am going to have it pulled again tomorrow so I will post it then.
Sounds like you might have oil on your MAF sensor. Could clean it off with MAF cleaner.
