I have a 2005 Limited 5.7. Sometimes when using reverse it will idle a little ruff and the idle doesn't move the vehicle so I have to give it some gas to get it moving, then when I shift into drive the engine dies. Any ideas?

I would clean the throttle body and idle air solenoid if it has one. I know on older models it was mounted to the side of the throttle body.

Could possibly be a vacuum leak.
