Ordering My New Cobalt Tomorrow.
But then I found this on this forum:

I was having that happen to me, give it a tune up, clean the maf, clean the throttle body, etc.
If the general maintenance doesn't work could be one of three things from what I have researched.
Throttle body assembly (I just replaced mine, I'll let you know how that goes in the week)
APPS (my DTC codes said it wasn't likely it was this part and more likely the TBA)
This is a very common problem on these balts, that has a ton of causes.
Left me a little scared. I dont think it will be a deal killer, just a little recent concern, now.
