02 trans am hesitates

I've got an o2 trans am ls1 and it will hesitate and act like its not getting gas, backfire and die but doesn't do it all the time... Any ideas?

I just had that same probably and I changed my fuel assembly out and haven't had that problem since. But now my cats are bad and its starting to hesitate again so i'm not thinking it might be either your cats or fuel regulator

Scan your check engine light and go from there, everything else is a wild guess...

Make sure you have a good temp sensor those will cause issues like you mention. I had mine go bad a month or two ago and was causing my car to buckle, backfire and not run right
