Angry 05 Cobalt Help!

Hello everyone, I am new to this place, so hello! But I have some questions about my 05 Cobalt. I just bought it around two weeks ago. I have a 4 door LS Copper Cobalt. I love my car so far! But I have been having some problems, and wanting to see if anyone can help me. First of all the same day I drove it off the lot, my check engine light came on. Well I took it to AutoZone to see what was wrong, they told me it was a Catalytic converter. Well I took it back to the dealership, and they sent it to a local Chevy dealership to get it replaced. Well I got it back, and the light was off for the rest of the day. Next day I was driving around, and it came back on. Now I dont know whats going on? Also, my car seems to be eatting gas like crazy! Whats up with that? It takes it about a two days to get down to a half tank? Anyone else have this problem? Please help me if you can! Thanks so much!

Sounds like the two are going hand in hand.. Your car is running rich for some odd reason and its eating gas and burning up your catalytic converter.. Take it back to the dealership and cause a fuss

I second, something like that is cause for concern. Take it back, and request another. If they dont give it to ya, cause a stink.

I need to take mine in for the same thing. But my light goes off after a couple weeks.... Makes me feel better, but I know, I still need to get it fixed before it turns into something worse.
Although my mileage doesn't seem to be hurt.

Minor mods... Wheels, de-badged & de-trimmed, stereo, grill, intake, eyelids.

Buddy of mine owns a SS (I've got a lowly LS). Anyway, his car (a stick) was running at high idle with a check engine light. First they told him it was the injectors. After searching around, they determined that a vacuum line running in the center console has worn through because of contact with the shafts connecting the gear shifter to the transmission. Replaced the vacuum line and POOF, problem solved.
