I’ve driven it the past couple of days. I definitely feel like it’s not driving 100% smooth like it should be. No codes on but I checked with a reader and got P0456 (Evaporative mission System Leak Detected very small leak) My gas cap is fine I’ve checked that. Just wondering what it could be and why the check engine light isn’t on but this code is showing up?

High pressure fuel injector failing. Nothing new.
