    When I start my blazer up in the morning it starts and idles fine. After it runs for 10 minutes or so and i go to drive the idle kicks down and everything. However, if i hit the gas to pull out of my neighborhood, the truck will stall, or come damn close. What could be causing this? Could it be a vacuum. After the first couple of minutes of driving there are no more problems.

    Well its pretty cold there in the mornings huh? A lot of GM cars and trucks do that in winter. May just be choke related, cleaning and adjustment time. I got mine to where I think it will never do it again , and we have a cold night and once in awhile it does it again. I have found letting it warm up a couple extra minutes helps /forums/images/graemlins/k5.gif

    Choke problem, not vacuum. Vacuum problem would be a problem right from the get go.
