    Newnan is where I got mine done. No questions asked. They’ve always been great to me. I think it must not be for the 4 cylinders. I’m not 100% sure though.

    Just so everyone knows I called Lagrange Toyota and they took my vin and said there is no tsb for the 4 bangers. If newnan would have told me this I wouldn’t had to argue with them. They were telling me it was my 2 inch lift that was causing my problems. Then I told them it was baloney then they said it was my Toyota trd rims with tires. So I call bologna on that too and told them that they were selling the same trucks with the same rims and same size tires so then they told me it was my exhaust and cold air intake then I just left the dealership.

    I had mine done last week while having blower motor recall done. Truck throttle response is so much better now.

    What octane are you running now? I MUST get this ECU update but wondering if running 87 is part of the problem..

    Running 87 is absolutely part of the problem. However i would say 85% of the issue is the transmission shift logic making your engine try to run at 1000 rpm. After the tsb, i notice it tries to stay above 1500 rpm, which helps a lot. Low rpm sputtering and missing has been solved with 91 octane. The detonation rattle at light throttle right before a downshift is also gone with 91 octane.

    Thank you that’s very helpful. We have 93 octane here, otherwise would have to use 89. I’ve read that high octane fuel in engines built for lower octane can negatively affect an engine over a long period of time. Any truth to that IYO? Would 93 be too high? Also, the TSB you are referring to... Was it the 0062-18 that helped? Thx in advance

    There is no harm in running 93. I have run it for 30k miles or so due to the low throttle miss. 89 probably would fix it as well, but I typically only have 87 or 93.

    I think thats an old wives tail. The missing is from the ecu retarding timing when it senses knock. Knock is bad. Retarding timing and running pig rich is bad. Thats the kind of stuff that hurts engines.

    Yeah my main issue is the way the truck shifts/runs through gears. Always wants to jump to 6th even though I’m running 30-35. If I try to ease on the pedal to increase speed a little or increase it gradually, it shimmies 1/2 the time and feels like having an MT in too high of a gear or like its missing or stalling. The only time it shifts through the gears appropriately is if I drive aggressively through each, and even then it typically touches 4th for a split second and skips to 5/6. Definitely didn’t act this way the first few days of driving it. When I’m driving in the country at 45, any incline or decline and it’s all over the place.

    I don't understand how some people are OK with this. If you average 20 mpg over the course of 100,000 miles, running high test the entire time would cost you another $2400 at today's fuel prices. That's a tough pill to swallow when the truck is supposed to run correctly on 87.

    Been to the dealer, they give me the ole can't replicate, even though it's doing it as they drive it... I come from turbo vehicles so 93 is not a big deal to me, but it may be to others.

    Never said I was ok with it, it just is what it is. I don't get 20 mpg's either lol.

    I just did my taxes and since my truck is a company truck, its pretty easy to track, I filled up 59 times last year. I spent probably about $275 dollars more on fuel than I should have had to for the year. It's not the end of the world to me.

    Did you have trouble getting them to do the update? Ive read some places are great and some don’t want to help. If it’s a programming thing, it’s super easy and seems like something they would gladly to do if you bought a truck from them.

    Hello, my friend. We’ve been down this road a time or two. Would it be nice if my truck ran right off the cheap stuff? Yes, yes it would. But, it won’t. So, I buy it the good stuff and it makes my life easier. It would also be nice if my wife liked cheaper clothing, purses, accessories, shoes, and you name it, but she doesn’t. So, I get her the good stuff too. That also makes my life easier. I like it that way. Hope all is well. :)

    P.S. I almost forgot, my truck apparently misses my friendly Toyota techs so it’s back in the shop again. It’s been there all week and not a peep. Three weeks last time so we will see how long this time. I developed a bad vibration after the rear differential was installed and the tranny pulled. We will see what the latest is in the next episode of “As the Taco Turns”.
