I have a 2007 Chevy Silverado with 82k miles on the 5.3L V8 motor w/ automatic transmission. I've had a problem with it stalling recently. It seems to happen mostly when the engine isn't "warm" yet, and I'm braking into a turn at low speeds. This morning it stalled while making a left turn out of my neighborhood doing aprox 10-15 miles per hour. I slipped it into Neutral, and restarted it while rolling. Drove another 100yds and it stalled again as I was breaking at a stop sign. then drove it another 30 minutes stopping and going many times, and it never stalled. What could it be?

    could be idle air control going bad but try cleaning the throttle body to start with. use a good throttle body cleaner or have it done.

    Try retorquing intake and check for other vacuum leak(s). Intake may reseal after expanding from warm up!
