    Default 06 Tundra 'Jerks' on acceleration at hwy speed

    I have an '06 Dbl-Cab Tundra with approx. 93k miles. Recently it began 'stumbling' on acceleration at highway speeds. I tried to be more attentive, and notice that it only happens at a speed of 50-60mph, approx 2000-2200rpm, when I ease down on the accelerator to slightly increase speed. It makes no difference what terrain (level or hill). I have no active codes, and the light has not come on. It feels like a misfire, but I can't rule-out the transmission shifting somehow and causing it, because I don't 'hear' anything, just feel the 'jerk'. Afterwards, I can accelerate and decelerate just fine with no more hesitation or jerking.
    Oh yea, to make it more perplexing, it doesn't always happen. It may happen several times one day, then not again for a week.
    I don't have any specialty Toyota tools, but I do have digital multi-meters, digital-storage o-scope, code-reader (Autozone model), and schematics from alldata if someone could point me in the right direction toward something to check.
    Thanks!

    It could be an issue with the torque converter and/or shift solenoids. I strongly urge you to do an Auto-Rx treatment, run it for 1,000-1,500 miles, then flush your tranny with Mobil 1 Synthetic ATF. The link to purchase is in my sig line.

    X2 what Remmy said. You may also want to clean the MAF and Throttle Body.

    I would check your throttle body. Take that sucker off and give it a really good cleaning. That many miles it isn't uncommon, and my Dad's truck (220,000 miles) did the same thing, but probably not as bad. Take that whole thing off, spray the inside out and clean it really well.

    +1 on cleaning throttle body. Also disconnect the battery for about 30 minutes to let the ECU reset, and have it relearn everything.

    "Tundra Jerks" sounds like a new forum.

    Thanks for all the excellent suggestions! I disconnected battery cable for about an hour while I cleaned the MAF-Sensor and throttle-body. They were both VERY dirty!
    I'm on my second tank of gas since this service, so it's probably still 'learning' everything again, but so-far it has not been jerking anymore. Hopefully I will see a little improvement in fuel economy also. I'm getting right at 15mpg. Just over 16mpg was the best I remember seeing, but that was shortly after I bought it.
    On the spark-plug thing. I bought a set of those Pulstar plugs and tried them last year. Within 1 month one had failed. They were kind enough to replace the entire set, but I never noticed any additional power or better fuel economy. After 3 months I had another one fail, and just put the factory irridium plugs back in. Haven't had an issue since. So if anyone's considering those, I wouldn't waste the $180. At least not for a Tundra.
    Thanks again to everyone for the help.
