Question about Toyota Sienna
No fault code where? on the Pro OBD2 scan tool screen>?
should be in warranty, why not let them fix it?
tow it there.?
bravo that, first post ever with fast right foot test, you are on the ball.
ok, that means this.
1: it's not losing 12vdc power to run the EFI. all lamps are not dim.
2: the fast foot test, implies to me, spark is ok, (unless one cylinder shut down, a bad COP?. but the scanner will see that for sure and did not. Gross misfire, is never unreported by the scan tool. (PCM)
gross enough to stall the engine.
so fueling issues.
id check for flooding or starving for fuel. and bad fuel.
Ok so my guess, is its losing fuel pressure or you got bad fuel.

I have a 85 coupe,the pumps are notorous for going out.Best bet is empty the whole tank.the pump .Is easy to pull its under the filler door.1 make sure its not your security system shutting off
your injectors .2 turn key in on poss and open gas door you should hear the motor.If not
disconnect batt and remove.be car e you dont lose the screen.once out dry off and hook up to any batt to check.there only 30 bucks but make sure you ground it out right and dont turn it on in a dry tank ,you will burn it out.

Engine stalls or RPM
fluctuates at idle up and down or dies near idle.
This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
