09 camery 2.4 vvti engine when I start the car in the mornings and it will start but dies start it again and again same thing shuts off as soon as it starts. if I wait a hour or so it will start up and run ok , the only other thing is that at stop lights it will idle but the idle will dip down a little it does not quit it just dips down just a little bit and back up to normal. I have cleaned the throttle body, mas air flow sensor, and I am not sure what else to do with it.
any idea would be great,

thanks.
