Hey so my 370z has been parked for the winter here in Illinois and I started it up for the first time I about two months. Car has been sitting since late October. When I started it up it had a rough idle and after several minutes the check engine light came on. Can someone help possibly diagnose this I can get code soon here but I bet it's just gonna be that pesky PO300 code. I was wondering since gas can go bad in 3-6 months of sitting is that possible? I doubt I'd need to spark plugs as it has 30k miles but I'm open to suggestions. Anything feedback helps thank you.
