    Hello all. I currently have a 2016 Tundra SR5 (2WD)58K miles, purchased used at 50K 6 months ago.
    I am experiencing a hesitation when accelerating, (local or highway traffic, not every time but more often than not).
    I have taken it back to the dealer to be diagnosed at least 5 times. The result is still the same
    "they feel the hesitation but cant pin point the cause". They claimed to have ran a diagnostic check and no problems. I was told they even did a pressure test on the fuel system. I use 87 octane fuel and I've even tried the higher octane with no improvements. Any advice or suggestions please.

    I think this is standard with these trucks. My 19 has a little bit of hesitation unless I put it in tow mode.

    Try pressing and holding the traction control button for three seconds. This will turn on the simulated limited slip and turn off traction control. You could then hit it for another three seconds and turn everything off. I tend to just do the first step as it keeps my truck from trying to cut power off the line if I need to get on it into traffic.

    Just a thought for something to try. Just to eliminate tire slippage chopping throttle.

    Higher octane only helps with detonation for higher compression ratios and typically, the 91/93 grades don’t have alcohol in them which is a more stable blend.

    My truck was slightly stumbling on startup and I did the following and it cleaned up the issues.
    1. Remove Clean the throttle body (be sure to use throttle body cleaner)
    2. Remove and clean MAF sensor (be sure to use MAF sensor cleaner)
    3. Run a can of BG44K through the gas tank.

    Coming to a Tundra from a 1997 T100 with 265,000 miles that I've done only routine maintenance to (never cleaned the MAF sensor) I'm surprised to see that it's considered a true option on a truck with just 58,000 miles to clean the MAF sensor. But these new fangled machines are possibly MUCH MORE finicky (thank you California).

    OP, have you disconnected the battery terminals for 15 full minutes to do an electric/electronic reset?

    Also (if you haven't already done another additive) consider running a 12 oz bottle of Techron through it (add to a full tank of gas).

    What a coincidence, mine has started doing this as well. I noticed on the interstate at about 70mph, my rpms jump slightly causing a rock back and forth if that makes sense. No warning lights, all I’ve done is clean the throttle body a few weeks ago and installed a drop in K&N. I did fill up with gas right before I noticed it so who knows.

    Maybe too much oil on the K&N. Possibly fouled up your MAF.

    Can’t rule that out. I’ll investigate and report back

    I hear ya. I also didn’t realize that my 2014 doesn’t have a fuel filter either? That was where my head was but when I went to get a fuel filter I discovered there isn’t one. So that left me with MAF sensor cleaning, TB cleaning and the BG44K fuel treatment. Not sure which one was the culprit but it made all the difference.

    Anyway, about the same time of the stumbling, I got a MAF code once so I cleaned it all together. I was surprised at how much gunk was caked inside the throttle body...I did all this at 60K, BTW.

    I clean the MAF sensors on all my vehicles frequently (every 10K miles). For as many miles I put on my vehicles per year (50-55K miles), having a poor running fuel injection systems isn't an option at 3.49 per gallon.
