Exhaust/Gas Smell

[Chris Barnes]

I have an intermittent issue where the car smells like exhaust/fuel. I've noticed it off and on lately and today it was so bad i could actually smell it through the vents when stopped in traffic. I've checked the injectors for leaks and don't see any evidence of anything leaking. My setup is a 2018 GT-A10 with Stage II P1X ProCharger, ID1050x injectors, UPR procharger catch can, Tial BOV and PBD tune. Car runs great and doesn't seem to have any issues. I'm wondering if it could be a bad evap/purge, charcoal canister or fuel tank seal? I would think it would pull a code if this were the case but was hoping someone else out there in 6G land could advise. Thanks much!

Sounds like there has to be a leak or broken / loose seal somewhere???

Worse or any difference with windows down? Just wondering if prevalent outside too or feeding to vents...

It's really bad when you first fire it up in the morning. I watch the AFR/Lambda while its running and it's perfect at 14.1/1.00 within 1-2%. Short term and long term fuel trims look great.
