The only time I've ever seen that code (not on a GTO) it had to do with low battery voltage during or prior to cranking and starting. In our case it turned out to be a bad connection at the starter on my wife's HHR. Other things could cause it like low battery voltage during starting, a bad ground cable etc. FWIW.

I never have troubles starting my car, i just turned the check engine off just last week and it still hasn't showed up ever since, battery is new, would i need to change the alternator maybe?

If the CEL hasn't come back just make sure your battery connections are good and you should be okay.
