    I just reread your original post, if you are thinking that it is an intake manifold gasket you can test it by spraying carb cleaner around the edges of it while the truck is running. if the RPMs increase then you found your issue.

    You won't have any luck checking vacume lines with soap solution unless you can pressurize them somehow. As Pikey suggests, try some carb cleaner sprayed around the mating surfaces and hoses while running and you will get a change in RPM if there is a leak.

    will throttle body cleaner work or does it have to be just carb cleaner?

    You had mentioned a drive by wire setup. is your engine drive by wire? Two things come to mind... first is the Idle Air Control may not be working correctly and second is the Exhaust Gas Recirculation valve may be stuck open. I am not familiar with the 03 and it may have both or neither. Are you able to start it back up Ok after it has died? Aside from a little load on the engine I can't imagine what steering iinput could affect.

    it fires right up no problem and will idle real good yes it is drive by wire

    this is only occuring when im slowing down the rpms drop an will sometimes die
    or when im in a parking lot and go to turn the wheel it will die

    i can leave it in park rev it a bit turn the wheel one way or the other and it wil die
