Bad O2 sensors causing idle problems?

I have a heads/cam ls1 that was running fine for quite a while until last week when I got an SES light. I checked the codes and they were for the front O2s (I don't have rears). Well since then the car has developed a real low idle, and when I give it gas it takes a few seconds for it to respond, which it usually does by lunging a little at that point. It seems like it's missins a lot throughout the lower RPMs. Do you guys think this problem is attributed to bad O2 sensors? If so, how? Thank you very much for any replies.

also for the hell of it check your maf and cleen it along with your TB thats what I'd do. make shure to unhook your battery befor removing your maf and hook it back up befor you put the battery back on.

i think i need o2s also. i keep getting a p0300 code(multiple missfire) and feels like it stumbles at idle a little bit. i'd say you need 02's, i think there like 45 bux each from gm
