    I have a 2016 FFV 5.7L V8 4x4 crewmax. I feel the need to notify the public that my car was having really really bad rough starts in the morning - didn’t matter if weather was cold or warm - first start of the day always sounded like the engine was choking. I googled online and found this site and many other message boards about the Alcohol Density Calculation problems and the need to “reflash” the ECM (see Toyota Service Bulletin T-SB-0058-13).
    I took the truck in to the dealer yesterday, they did a cold start this morning after it sat in the lot overnight, and concluded it had this problem that is specific to FFV Tundra engines.
    The service advisor said that Toyota just came out with a new TSB a few days ago updating the old TSB so that it now covers the fuel pump and the “reflashing” of the ECM, it now also covers all FFV Tundras from 2009 - 2019. The new TSB is T-SB-0166-19.
    So I hope this info helps, hit up your dealer if you are having engine start-up problems with your FFV engine Tundras, and pass the word around!
    If I had known about these engine issues, I would have NEVER bought a FFV engine!!!

    You didn't have much choice in certain areas of the country from 14 to 18-19. I've noticed they've dropped some of the requirements. Now, you see very few FFV around. Then, you couldn't find an non-FFV at all. I personally never had an issue with my 14 FFV.

    Target612 just wants others to feel his pain over the issues his truck is having. Occasional light trolling is one thing but bumping multiple old threads using the same long winded post is a bit much.

    Mods, where are you?
