2006 Toyota Tundra. Engine size = V8.
Warning lights = maintenance required  light on.

I started my truck as I normally do and it revved up but then just idled down and died. I tried
several times to restart and the same thing happened. I tried to increase idle and even put the
vehicle in gear and tried to move it but it kept dying.
The maintenance required light should have nothing to do with the fact the truck is running
like this. You may have a large vacuum leak causing it to stall when it idles down. Possibly
carbon buildup in the throttle or a problem with the throttle or idle air control. Check for a
vacuum leak first then get the computer codes scanned. Many of the large national parts
store chains will do this for free.
Tundra- Did all except scan codes and then took it to mechanic but I noticed a wire that
had been chewed by mouse or squirrel. This wire attached to a module mounted on the
fender well passenger side. I pointed this out to mechanic and at first he did not think this
was the problem. When hooked up to diagnostic nothing came up so he repaired the wire
and the truck started right away and had no problems. Still don't know what that module is?
It's the ignition module.

Warning lights- Air Bag light. No code been found.
Air bag light is on, I have disconnect the battery and connect back, as soon I drove the car air
bag light come on. I took to the mechanic to diagnose the problem but he couldn't find any code.
If the
airbag light is or was on, then there are codes stored in the computer. It is possible his
scanner cannot read the airbag computer, or the computer is malfunctioning. A mechanic
would have to diagnose the problem of no codes. If that means he cannot communicate with
the module, then that is the place to start.
2005 Toyota Camry idle is too low. How can i adjust idle up
There is no adjustment  for the idle speed. I would say
you probably have carbon buildup in the throttle that
needs to be cleaned out.
