Diag vsc 51

Has Anyone dealt with this rabbit trail? Thus far i've cleaned my MAF and replace gas cap with no luck.
Autozone OBD II scanner reads P0455, or P0456

P0455 is gross evap leak. check gas cap is on right and the seal is good. If ok you will have to smoke the evap system to find the leak

Tried a new gas cap, still no change.
Disconnect the negative battery terminal for 5 minutes and it cleared that stupid code.
I was about to do my O2 sensors and OMG that's a lot of work to change those sensors

The codes will come back you need to get it smoked. You should see a green cap in the engine compartment this is where the smoke machine connects to. most likely have a fuel vapor line thats cracked
