Thumbs down Low RPM Idle

Recently, my 2005 Cobalt LS has been sounding pretty rough while idling. Sounds like shes about to stall out when Im sitting at red lights or at any kind of stop. Any ideas why this is happening??



Update: Check below for the solution to this problem

No it doesnt say that.
There has been one weird thing that has been happening that i have NEVER seen come up, CHECK GAS CAP. But, i refueled recently and it hasnt come up on the display. Like I said, those are the only things ive noticed differently...

Have you replaced your fuel filter? If I am not mistaken you are getting up there in miles. It might not be the cause, but I do know that a clogged fuel filter can cause low idle, and not throw a code on OBD II cars.

Def. time for a fuel filter, besides, it's only about $10.00
