Alright so I have stored my 370z this winter and I a. Afraid the gas has gone bad somewhat. It rough idles, and doesn't sound quite right in the exhaust. Almost a little bit choppy. I saw this thread and was wondering if anyone has any idea on how to go about fixing the issue. It's a 2019 with 30k miles so spark plugs seem unlikely. There was no vacuum leaks. I was just wondering if anyone knew how to go about diagnosing that and potential fixes.
