2007 Toyota Tundra v-8, 5. 7 l. 4 lo light blinks, vsc light blink, check engine light on continuously all three of these lights are coming on. I can take my battery off and they reset. Per Toyota disconnect battery and it will re set. The truck will kick you down to 40 mph or slower when this happens even if you are running 60 at the time. Was told the problem was my secondary air intake. And a tire sensor problem. But that doesn't explain the sudden surges in motor or dieing for no reason. Talked with Toyota and they said they would fix it. To date not done. This has happened for the past 2 months. Have to disconnect my battery several times a day just to drive my truck. I have almost been hit more than 3 times due to this problem. Went to pull out to cross 3 lanes of traffic and it kicked down, had the gas pedal floored and the truck would barely move. My truck now has 40,000 miles and it still is not fixed. My a/c went out, said it was the fuse, what about the blower motor that has never worked right, or the truck wants to die all the time, electronic start wont work was told my battery was no good yet they won't honor the battery because it is now out of their warranty due to them taking so long to get it in and having me to disconnect the battery all the time. Toyota called to day and said my truck would be done in a couple hours, then less than a hour later they said it wouldn't be done because they had ordered the wrong parts and that I would need to bring them a battery.
