06 Chevy Cobalt LT idling rough-sputtering

Asked by Sep 23, 2016 at 07:11 PM about the 2006 Chevrolet Cobalt LT

Question type: Maintenance & Repair

My Chevy Cobalt LT 2006 is idling hard whenever I
have it stopped. Driving is fine. No problems when
driving. When stopped, in Drive or Park, it idles
rough, lights dimming, acting like it's going to shut
off, idle is between 500-800rpm.
So far, I've cleaned the entire fueling system and
replaced spark plugs, replaced throttle body.
I've spent about $900 doing all this and it's not
fixing it. I've had Midas do all the work. My credit
card is maxed out. They said that a fuel induction
would fix it 3 weeks ago. Well we did that, and then
the check engine light came on yesterday.
So today they changed the throttle body. As I was
driving home, check engine light came on again and
it's doing the same thing they said that getting a
new Throttle body would fix!!!!!
What is wrong with my car????

I presume they're scanning it for trouble codes before they embark upon these repair projects, right?

Yes, of course.
