Loose connection somewhere.

 

this kinda happened to me in my 06 SS/SC the power wire on the started wasnt making a good connection and it was screwing everything up

 

My guages flicker after I turn off my car, I think it happens on all cobalts like some kind of self check. As far as your problem sounds like a connection problem.

 

Mine did that periodically, found out it was the power steering motor going bad, drawing to much current, got the recall done and it hasnt happened since

 

Could also be your ignition switch.
Do you have a wad of keys on the keyring?if so take them off.

 

haha i got it i blew *4 fuses wow
