    Looks like that Italian tune-up did the trick! Phew!

    This reminds me of my 2014 Tundra a few year back. I was annoyed it has no locking gas cap so open for folks stealing gas. So I bought a locking gas cap off Amazon (big mistake.) It said it fit my Toyota and I didn't see negative reviews. (It has one, now.)
    Anyway, about 2 days after installing it, I started up the truck and it made a backfire bang and I saw a huge plume of smoke come out and I got a check engine light....crap! I looked up the engine code and it was for the evap system and I knew it was the POC cap. Threw it away and put the old one back on. (I had saved it, thank Goodness!)
