Hey guys! So i just got an 05 cobalt. Test drove it and it seemed fine but... On the way home form the dealer it was acting up a bit... I went to pull out of a gas station and it stalled out.. I restarted and kept driving but when i would slow down and come to a stop, the idle drops low and the lights dim like its about to stall out again, then it idles back up, then drops low again and it feels like its gonna die again... Then it goes back to normal idle... I would say its a IAC but I don't know enough about these to be sure... Has anyone else had this problem?? Other than that, everything else seems fine. Trans works fine, plenty of power, ect... Any help would be great! Thanks!
